New research puts to death the “good guy with a gun” narrative

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

There are also measurable increases in murder charges filed in states after stand your ground laws are passed.

What a load of crap.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2). By comparison, Lott and Mustard found the concealed weapon dummy variable to be associated with a 7.65 percent reduction in total homicides across all counties and a 9 percent reduction in homicides when only large counties (populations of 100,000 or more) were included.43

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

Abstract: In an article published in 2011, Aneja, Donohue and Zhang found that shall-issue or right-to-carry (RTC) concealed weapons laws have no effect on any crime except for a positive effect on assault.

This paper reports a replication of their basic findings and some corresponding robustness checks, which reveal a serious omitted variable problem.

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

“The Debate on Shall-Issue Laws” by Carlisle e. Moody and Thomas B. Marvell, published in Econ Journal Watch, volume 5, number 3, September 2008 It is also available here..


Summary and Conclusion

Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years

. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime.

Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering.

We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend.

These results are very similar to those of Ayres and Donohue, properly interpreted.

The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review

Abstract
“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.
Summary and Conclusion Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

We acknowledge that, especially in light of the methodological issues of the literature in general, the magnitudes derived from our analysis of crime statistics and the supposed costs of crime might be dwarfed by other considerations in judging the policy issue. Some might contend that allowing individuals to carry a concealed weapon is a moral or cultural bad. Others might contend that greater liberty is a moral or cultural good. All we are confident in saying is that the evidence, such as it is, seems to support the hypothesis that the shall-issue law is generally beneficial with respect to its overall long run effect on crime.

Okay again , the violent crime rates across the board have been going down. My study specifically makes the connection between gun ownership and GUN DEATHS SPECIFICALLY. Your so called studies are simply looking at crime trends that have already been going down anyway.

No...it doesn't.....it tries to link concealed carry to mass public shootings and I showed you how even the simplest question debunks the entire study on that point........

The study you found claims concealed carry gun permit numbers increase mass public shootings....I showed you that this is stupid and dumb as a claim...

You can't explain the link either...

Mass public shooters don't need a concealed carry permit to carry the gun to the place where they plan on committing mass murder.......

Criminals who can't legally buy, own or carry guns, can't get a legal carry permit to carry their already illegal gun.......and they are the ones committing almost all of the murder in this country in democrat party controlled cities...

Your study is crap.......

What the article says is that looser concealed carry laws contribute to more gun deaths in general - not just mass shootings. As a separate point, it says the good guy with a gun idea doesn’t affect mass shootings.

It can't prove that since making a connection between law abiding permit holders makes no sense...since the majority of all crime and gun murder is committed by people who can't legally have a gun permit for their already illegal guns.........

And I just posted other real studies showing that concealed carry, in fact, helps to reduce the crime rate......

Here is my request because I don't have the patience to read your wall post bullshit. Cite me ONE study, with a link, that shows in a given area, concealed carry reduced the crime rate in that specific area. Don't give me national crime statistics. I want crime statistics for a specific area.

And here....

CONCLUSION It is difficult to make a strong conclusion on the impact concealed carry permits have on crime because there are studies that show contradictory results. However, based on the thorough research conducted by John R. Lott (2003), the evidence from the case study in Dade County, and the research conducted by Kleck and Mertz (1995), it appears that benefits of allowing law abiding citizens to carry a concealed weapon outweigh the negatives that guns can bring upon a society. The concerns mentioned above against the policy are not substantiated by the evidence available. The evidence suggests that children are more likely to drown or die in a bicycle accident then they are to die from a loaded unlocked gun. In addition, private gun owners are far less likely to mistakenly kill someone then a police officer is (Lott Jr., 1998). Ultimately the policy appears to be effective in terms of crime reduction.

We’re looking for studies that weren’t funded by the NRA.

The entire reason the CDC stopped studying gun violence is that every study on gun violence said that reducing the number of guns would reduce the number of gun related deaths in the country. Republicans responded cancelling all such research.

You are a liar......you know, from having been shown over and over again, in thread after thread, that the CDC did not stop researching gun violence......having been shown gun research conducted by the CDC ....you are an asshole...

You can lie about the facts...but you can't do it here....

==================

The Deleware study of 2015...

When Gun Violence Felt Like a Disease, a City in Delaware Turned to the C.D.C.

When epidemiologists from the Centers for Disease Control and Prevention came to this city, they were not here to track an outbreak of meningitis or study the effectiveness of a particular vaccine.

They were here to examine gun violence.
This city of about 70,000 had a 45 percent jump in shootings from 2011 to 2013, and the violence has remained stubbornly high; 25 shooting deaths have been reported this year, slightly more than last year, according to the mayor’s office
.-------

The final report, which has been submitted to the state, reached a conclusion that many here said they already knew: that there are certain patterns in the lives of many who commit gun violence.
“The majority of individuals involved in urban firearm violence are young men with substantial violence involvement preceding the more serious offense of a firearm crime,” the report said. “Our findings suggest that integrating data systems could help these individuals better receive the early, comprehensive help that they need to prevent violence involvement.”
Researchers analyzed data on 569 people charged with firearm crimes from 2009 to May 21, 2014, and looked for certain risk factors in their lives, such as whether they had been unemployed, had received help from assistance programs, had been possible victims of child abuse, or had been shot or stabbed. The idea was to show that linking such data could create a better understanding of who might need help before becoming involved in violence.

Why Congress stopped gun control activism at the CDC

I was one of three medical doctors who testified before the House’s Labor, Health, Human Services, and Education Appropriations Subcommittee on March 6, 1996 about the CDC’s misdeeds. (Note: This testimony and related events are described in my three-part documented historical series). Here is what we showed the committee:

• Dr. Arthur Kellermann’s1993 New England Journal of Medicine article that launched his career as a rock star gun control advocate and gave rise to the much-repeated “three times” fallacy. His research was supported by two CDC grants.

Kellermann and his colleagues used the case control method, traditionally an epidemiology research tool, to claim that having a gun in the home triples the risk of becoming a homicide victim. In the article Kellermann admitted that “a majority of the homicides (50.9 percent) occurred in the context of a quarrel or a romantic triangle.” Still another 30 percent “were related to drug dealing” or “occurred during the commission of another felony, such as a robbery, rape, or burglary.”

In summary, the CDC funded a flawed study of crime-prone inner city residents who had been murdered in their homes. The authors then tried to equate this wildly unrepresentative group with typical American gun owners. The committee members were not amused.

• The Winter 1993 CDC official publication, Public Health Policy for Preventing Violence, coauthored by CDC official Dr. Mark Rosenberg. This taxpayer-funded gun control polemic offered two strategies for preventing firearm injuries—“restrictive licensing (for example, only police, military, guards, and so on)” and “prohibit gun ownership.”
• The brazen public comments of top CDC officials, made at a time when gun prohibitionists were much more candid about their political goals.

“We’re going to systematically build a case that owning firearms causes deaths. We’re doing the most we can do, given the political realities.” (P.W. O’Carroll, Acting Section Head of Division of Injury Control, CDC, quoted in Marsha F. Goldsmith, “Epidemiologists Aim at New Target: Health Risk of Handgun Proliferation,” Journal of the American Medical Association vol. 261 no. 5, February 3, 1989, pp. 675-76.) Dr. O’Carroll later said he had been misquoted.

But his successor Dr. Mark Rosenberg was quoted in the Washington Post as wanting his agency to create a public perception of firearms as “dirty, deadly—and banned.” (William Raspberry, “Sick People With Guns,” Washington Post, October 19, 1994.

• CDC Grant #R49/CCR903697-06 to the Trauma Foundation, a San Francisco gun control advocacy group, supporting a newsletter that frankly advocated gun control.

Moron, none of those studies come from the NRA....while the studies numb nuts posted are directly from anti-gun extremists.

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2).

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

Abstract: In an article published in 2011, Aneja, Donohue and Zhang found that shall-issue or right-to-carry (RTC) concealed weapons laws have no effect on any crime except for a positive effect on assault.

This paper reports a replication of their basic findings and some corresponding robustness checks, which reveal a serious omitted variable problem.

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

Summary and Conclusion

Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years

. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime.

Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering.

We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend.

These results are very similar to those of Ayres and Donohue, properly interpreted.

The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review

Abstract
“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.

All we are confident in saying is that the evidence, such as it is, seems to support the hypothesis that the shall-issue law is generally beneficial with respect to its overall long run effect on crime.

Okay again , the violent crime rates across the board have been going down. My study specifically makes the connection between gun ownership and GUN DEATHS SPECIFICALLY. Your so called studies are simply looking at crime trends that have already been going down anyway.

No...it doesn't.....it tries to link concealed carry to mass public shootings and I showed you how even the simplest question debunks the entire study on that point........

The study you found claims concealed carry gun permit numbers increase mass public shootings....I showed you that this is stupid and dumb as a claim...

You can't explain the link either...

Mass public shooters don't need a concealed carry permit to carry the gun to the place where they plan on committing mass murder.......

Criminals who can't legally buy, own or carry guns, can't get a legal carry permit to carry their already illegal gun.......and they are the ones committing almost all of the murder in this country in democrat party controlled cities...

Your study is crap.......

What the article says is that looser concealed carry laws contribute to more gun deaths in general - not just mass shootings. As a separate point, it says the good guy with a gun idea doesn’t affect mass shootings.

It can't prove that since making a connection between law abiding permit holders makes no sense...since the majority of all crime and gun murder is committed by people who can't legally have a gun permit for their already illegal guns.........

And I just posted other real studies showing that concealed carry, in fact, helps to reduce the crime rate......

Here is my request because I don't have the patience to read your wall post bullshit. Cite me ONE study, with a link, that shows in a given area, concealed carry reduced the crime rate in that specific area. Don't give me national crime statistics. I want crime statistics for a specific area.

And here....

CONCLUSION It is difficult to make a strong conclusion on the impact concealed carry permits have on crime because there are studies that show contradictory results. However, based on the thorough research conducted by John R. Lott (2003), the evidence from the case study in Dade County, and the research conducted by Kleck and Mertz (1995), it appears that benefits of allowing law abiding citizens to carry a concealed weapon outweigh the negatives that guns can bring upon a society. The concerns mentioned above against the policy are not substantiated by the evidence available. The evidence suggests that children are more likely to drown or die in a bicycle accident then they are to die from a loaded unlocked gun. In addition, private gun owners are far less likely to mistakenly kill someone then a police officer is (Lott Jr., 1998). Ultimately the policy appears to be effective in terms of crime reduction.

Shall issue has its own set of variables. I mean this legislation is geared toward specific, vetted people. They are people with specific needs and are therefore the kind of people we know wouldn't be violent. This does not apply to the general statistics around concealed carry which results in all kinds of people owning guns even if they aren't convicted felons. The point in the abstract doesn't actually explain why these crime rates are lower.

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Here...actual research proving you wrong...

Okay again , the violent crime rates across the board have been going down. My study specifically makes the connection between gun ownership and GUN DEATHS SPECIFICALLY. Your so called studies are simply looking at crime trends that have already been going down anyway.

No...it doesn't.....it tries to link concealed carry to mass public shootings and I showed you how even the simplest question debunks the entire study on that point........

The study you found claims concealed carry gun permit numbers increase mass public shootings....I showed you that this is stupid and dumb as a claim...

You can't explain the link either...

Mass public shooters don't need a concealed carry permit to carry the gun to the place where they plan on committing mass murder.......

Criminals who can't legally buy, own or carry guns, can't get a legal carry permit to carry their already illegal gun.......and they are the ones committing almost all of the murder in this country in democrat party controlled cities...

Your study is crap.......

What the article says is that looser concealed carry laws contribute to more gun deaths in general - not just mass shootings. As a separate point, it says the good guy with a gun idea doesn’t affect mass shootings.

It can't prove that since making a connection between law abiding permit holders makes no sense...since the majority of all crime and gun murder is committed by people who can't legally have a gun permit for their already illegal guns.........

And I just posted other real studies showing that concealed carry, in fact, helps to reduce the crime rate......

Here is my request because I don't have the patience to read your wall post bullshit. Cite me ONE study, with a link, that shows in a given area, concealed carry reduced the crime rate in that specific area. Don't give me national crime statistics. I want crime statistics for a specific area.

Here....no permits needed to carry guns...

Top Three Rated "Safe States" are Constitutional Carry States

US News and World Report rates the states for public safety. The rating takes both property crime and violent crime into account. The ratings use the Federal Bureau of Investigation (FBI) data from 2017 for the article this year, as the latest data available.
The top three states for public safety this year are Maine, Vermont, and New Hampshire. All three are Constitutional Carry states, which means no permit is required to carry a loaded handgun in most public places, openly, or concealed. That was the state of the law in the nation when the Constitution was ratified on 4 March, 1789. Constitutional carry existed in all states for the first four decades of the Republic. Then states and the courts started chipping away at the Second Amendment.

Meh, It's something I guess. The problem is that it doesn't do anything to analyze the actual data. It just looks at three states as a whole. It doesn't do any look at variables that might contribute to WHY this is. Perhaps these states are safer for a myriad of reasons and not simply because of these particular gun laws.

Here is what my study did. It broke down actual variables and mitigated other factors.

"Emma Fridel, an assistant professor at Florida State University who authored the study, measured the affects of gun ownership rates and concealed-carry laws in all 50 states from 1991 to 2016. She controlled for other factors that might influence mass shooting and homicide rates, like unemployment rates, poverty levels and states' mental health expenditures."

"Her findings show that looser concealed-carry laws had little impact on mass shootings and increased a state's gun homicide rate by 11%. Higher rates of firearm ownership overall, meanwhile, was associated with a 53.5% increase in the likelihood of a mass shooting."

And with little effort we wrecked her study..........

You can keep lying all you want, her study is crap.

You know what she didn't control for? The policies of the democrat party on the murder rates.....the revolving door for known, violent, repeat gun offenders who have their arrests overturned, and plea bargained down and judges who let repeat, violent criminals out on bail over and over again....

That is what drives the gun crime rate in democrat party controlled cities...not normal people who own and carry guns for self defense....

You don't want to hear about that, because that is the real problem, you just hate guns.

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2). By comparison, Lott and Mustard found the concealed weapon dummy variable to be associated with a 7.65 percent reduction in total homicides across all counties and a 9 percent reduction in homicides when only large counties (populations of 100,000 or more) were included.43

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

Abstract: In an article published in 2011, Aneja, Donohue and Zhang found that shall-issue or right-to-carry (RTC) concealed weapons laws have no effect on any crime except for a positive effect on assault.

This paper reports a replication of their basic findings and some corresponding robustness checks, which reveal a serious omitted variable problem.

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

“The Debate on Shall-Issue Laws” by Carlisle e. Moody and Thomas B. Marvell, published in Econ Journal Watch, volume 5, number 3, September 2008 It is also available here..


Summary and Conclusion

Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years

. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime.

Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering.

We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend.

These results are very similar to those of Ayres and Donohue, properly interpreted.

The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review

Abstract
“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.

CONCLUSION It is difficult to make a strong conclusion on the impact concealed carry permits have on crime because there are studies that show contradictory results. However, based on the thorough research conducted by John R. Lott (2003), the evidence from the case study in Dade County, and the research conducted by Kleck and Mertz (1995), it appears that benefits of allowing law abiding citizens to carry a concealed weapon outweigh the negatives that guns can bring upon a society. The concerns mentioned above against the policy are not substantiated by the evidence available. The evidence suggests that children are more likely to drown or die in a bicycle accident then they are to die from a loaded unlocked gun. In addition, private gun owners are far less likely to mistakenly kill someone then a police officer is (Lott Jr., 1998). Ultimately the policy appears to be effective in terms of crime reduction.

https://econjwatch.or

Shall issue has its own set of variables. I mean this legislation is geared toward specific, vetted people. They are people with specific needs and are therefore the kind of people we know wouldn't be violent. This does not apply to the general statistics around concealed carry which results in all kinds of people owning guns even if they aren't convicted felons. The point in the abstract doesn't actually explain why these crime rates are lower.

Sorry, you are wrong.....

Again...27 years......we went from 4.7 million people with permits to carry guns to over 18.6 million people....and our gun murder rate went down 49%, our gun crime rate went down 75%...

You can't explain that...neither can she.....

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

Summary and Conclusion

Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years

. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime.

Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering.

We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend.

These results are very similar to those of Ayres and Donohue, properly interpreted.

The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review

Abstract
“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.

All we are confident in saying is that the evidence, such as it is, seems to support the hypothesis that the shall-issue law is generally beneficial with respect to its overall long run effect on crime.

Okay again , the violent crime rates across the board have been going down. My study specifically makes the connection between gun ownership and GUN DEATHS SPECIFICALLY. Your so called studies are simply looking at crime trends that have already been going down anyway.

No...it doesn't.....it tries to link concealed carry to mass public shootings and I showed you how even the simplest question debunks the entire study on that point........

The study you found claims concealed carry gun permit numbers increase mass public shootings....I showed you that this is stupid and dumb as a claim...

You can't explain the link either...

Mass public shooters don't need a concealed carry permit to carry the gun to the place where they plan on committing mass murder.......

Criminals who can't legally buy, own or carry guns, can't get a legal carry permit to carry their already illegal gun.......and they are the ones committing almost all of the murder in this country in democrat party controlled cities...

Your study is crap.......

What the article says is that looser concealed carry laws contribute to more gun deaths in general - not just mass shootings. As a separate point, it says the good guy with a gun idea doesn’t affect mass shootings.

It can't prove that since making a connection between law abiding permit holders makes no sense...since the majority of all crime and gun murder is committed by people who can't legally have a gun permit for their already illegal guns.........

And I just posted other real studies showing that concealed carry, in fact, helps to reduce the crime rate......

Here is my request because I don't have the patience to read your wall post bullshit. Cite me ONE study, with a link, that shows in a given area, concealed carry reduced the crime rate in that specific area. Don't give me national crime statistics. I want crime statistics for a specific area.

Here....no permits needed to carry guns...

Top Three Rated "Safe States" are Constitutional Carry States

US News and World Report rates the states for public safety. The rating takes both property crime and violent crime into account. The ratings use the Federal Bureau of Investigation (FBI) data from 2017 for the article this year, as the latest data available.
The top three states for public safety this year are Maine, Vermont, and New Hampshire. All three are Constitutional Carry states, which means no permit is required to carry a loaded handgun in most public places, openly, or concealed. That was the state of the law in the nation when the Constitution was ratified on 4 March, 1789. Constitutional carry existed in all states for the first four decades of the Republic. Then states and the courts started chipping away at the Second Amendment.

Meh, It's something I guess. The problem is that it doesn't do anything to analyze the actual data. It just looks at three states as a whole. It doesn't do any look at variables that might contribute to WHY this is. Perhaps these states are safer for a myriad of reasons and not simply because of these particular gun laws.

Here is what my study did. It broke down actual variables and mitigated other factors.

"Emma Fridel, an assistant professor at Florida State University who authored the study, measured the affects of gun ownership rates and concealed-carry laws in all 50 states from 1991 to 2016. She controlled for other factors that might influence mass shooting and homicide rates, like unemployment rates, poverty levels and states' mental health expenditures."

"Her findings show that looser concealed-carry laws had little impact on mass shootings and increased a state's gun homicide rate by 11%. Higher rates of firearm ownership overall, meanwhile, was associated with a 53.5% increase in the likelihood of a mass shooting."

And with little effort we wrecked her study..........

You can keep lying all you want, her study is crap.

You know what she didn't control for? The policies of the democrat party on the murder rates.....the revolving door for known, violent, repeat gun offenders who have their arrests overturned, and plea bargained down and judges who let repeat, violent criminals out on bail over and over again....

That is what drives the gun crime rate in democrat party controlled cities...not normal people who own and carry guns for self defense....

You don't want to hear about that, because that is the real problem, you just hate guns.

Lol quit pretending YOU wrecked anything. She obviously is a qualified researhcer. You are not. As for democrats? You didn't control for them either lol.

 

[Billy000]

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Here...actual research proving you wrong...

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2). By comparison, Lott and Mustard found the concealed weapon dummy variable to be associated with a 7.65 percent reduction in total homicides across all counties and a 9 percent reduction in homicides when only large counties (populations of 100,000 or more) were included.43

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

CONCLUSION It is difficult to make a strong conclusion on the impact concealed carry permits have on crime because there are studies that show contradictory results. However, based on the thorough research conducted by John R. Lott (2003), the evidence from the case study in Dade County, and the research conducted by Kleck and Mertz (1995), it appears that benefits of allowing law abiding citizens to carry a concealed weapon outweigh the negatives that guns can bring upon a society. The concerns mentioned above against the policy are not substantiated by the evidence available. The evidence suggests that children are more likely to drown or die in a bicycle accident then they are to die from a loaded unlocked gun. In addition, private gun owners are far less likely to mistakenly kill someone then a police officer is (Lott Jr., 1998). Ultimately the policy appears to be effective in terms of crime reduction.

We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering. We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend. These results are very similar to those of Ayres and Donohue, properly interpreted. The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review. We acknowledge that, especially in light of the methodological issues of the literature in general, the magnitudes derived from our analysis of crime statistics and the supposed costs of crime might be dwarfed by other considerations in judging the policy issue. Some might contend that allowing individuals to carry a concealed weapon is a moral or cultural bad. Others might contend that greater liberty is a moral or cultural good. All we are confident in saying is that the evidence, such as it is, seems to support the hypothesis that the shall-issue law is generally beneficial with respect to its overall long run effect on crime.

Shall issue has its own set of variables. I mean this legislation is geared toward specific, vetted people. They are people with specific needs and are therefore the kind of people we know wouldn't be violent. This does not apply to the general statistics around concealed carry which results in all kinds of people owning guns even if they aren't convicted felons. The point in the abstract doesn't actually explain why these crime rates are lower.

Sorry, you are wrong.....

Again...27 years......we went from 4.7 million people with permits to carry guns to over 18.6 million people....and our gun murder rate went down 49%, our gun crime rate went down 75%...

You can't explain that...neither can she.....

Crime itself is down all over the nation and there are many factors for this. That's why it matters to do more localized research and look at the variables involved. Your national crime rate statistics can be attributed to myriad of reasons. You simply wanting to make it all about gun laws is dumb.

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

Bullshit. The crime rate went down in every state that adopted concealed carry. It's almost certain the study is based on flawed assumptions.

CRIME rates have gone down in EVERY state, dipshit. Crime rates have been dropping in every state for more than 20 years.

MURDER RATES go up every time a state loosens concealed carry laws, or passes “stand your ground” laws, despite the overall drop in other crimes.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2). By comparison, Lott and Mustard found the concealed weapon dummy variable to be associated with a 7.65 percent reduction in total homicides across all counties and a 9 percent reduction in homicides when only large counties (populations of 100,000 or more) were included.43

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

Abstract: In an article published in 2011, Aneja, Donohue and Zhang found that shall-issue or right-to-carry (RTC) concealed weapons laws have no effect on any crime except for a positive effect on assault.

This paper reports a replication of their basic findings and some corresponding robustness checks, which reveal a serious omitted variable problem.

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

Summary and Conclusion

Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years

. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime.

Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering.

We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend.

Abstract
“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.

Okay again , the violent crime rates across the board have been going down. My study specifically makes the connection between gun ownership and GUN DEATHS SPECIFICALLY. Your so called studies are simply looking at crime trends that have already been going down anyway.

No...it doesn't.....it tries to link concealed carry to mass public shootings and I showed you how even the simplest question debunks the entire study on that point........

The study you found claims concealed carry gun permit numbers increase mass public shootings....I showed you that this is stupid and dumb as a claim...

You can't explain the link either...

Mass public shooters don't need a concealed carry permit to carry the gun to the place where they plan on committing mass murder.......

Criminals who can't legally buy, own or carry guns, can't get a legal carry permit to carry their already illegal gun.......and they are the ones committing almost all of the murder in this country in democrat party controlled cities...

Your study is crap.......

What the article says is that looser concealed carry laws contribute to more gun deaths in general - not just mass shootings. As a separate point, it says the good guy with a gun idea doesn’t affect mass shootings.

It can't prove that since making a connection between law abiding permit holders makes no sense...since the majority of all crime and gun murder is committed by people who can't legally have a gun permit for their already illegal guns.........

And I just posted other real studies showing that concealed carry, in fact, helps to reduce the crime rate......

Here is my request because I don't have the patience to read your wall post bullshit. Cite me ONE study, with a link, that shows in a given area, concealed carry reduced the crime rate in that specific area. Don't give me national crime statistics. I want crime statistics for a specific area.

Here....no permits needed to carry guns...

Top Three Rated "Safe States" are Constitutional Carry States

US News and World Report rates the states for public safety. The rating takes both property crime and violent crime into account. The ratings use the Federal Bureau of Investigation (FBI) data from 2017 for the article this year, as the latest data available.
The top three states for public safety this year are Maine, Vermont, and New Hampshire. All three are Constitutional Carry states, which means no permit is required to carry a loaded handgun in most public places, openly, or concealed. That was the state of the law in the nation when the Constitution was ratified on 4 March, 1789. Constitutional carry existed in all states for the first four decades of the Republic. Then states and the courts started chipping away at the Second Amendment.

This blogger is NOT a credible source.

Every unbiased study ever done has found otherwise. That protestor in Houston was shot because he had a legal firearm in his hands when he approached the car.

Lott (2003), the evidence from the case study in Dade County, and the research conducted by Kleck and Mertz (1995), it appears that benefits of allowing law abiding citizens to carry a concealed weapon outweigh the negatives that guns can bring upon a society. The concerns mentioned above against the policy are not substantiated by the evidence available. The evidence suggests that children are more likely to drown or die in a bicycle accident then they are to die from a loaded unlocked gun. In addition, private gun owners are far less likely to mistakenly kill someone then a police officer is (Lott Jr., 1998). Ultimately the policy appears to be effective in terms of crime reduction.

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2). By comparison, Lott and Mustard found the concealed weapon dummy variable to be associated with a 7.65 percent reduction in total homicides across all counties and a 9 percent reduction in homicides when only large counties (populations of 100,000 or more) were included.43

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

Abstract: In an article published in 2011, Aneja, Donohue and Zhang found that shall-issue or right-to-carry (RTC) concealed weapons laws have no effect on any crime except for a positive effect on assault.

This paper reports a replication of their basic findings and some corresponding robustness checks, which reveal a serious omitted variable problem.

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

“The Debate on Shall-Issue Laws” by Carlisle e. Moody and Thomas B. Marvell, published in Econ Journal Watch, volume 5, number 3, September 2008 It is also available here..


Summary and Conclusion

Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years

. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime.

Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering.

We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend.

These results are very similar to those of Ayres and Donohue, properly interpreted.

The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review

Abstract
“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.
Summary and Conclusion Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review. We acknowledge that, especially in light of the methodological issues of the literature in general, the magnitudes derived from our analysis of crime statistics and the supposed costs of crime might be dwarfed by other considerations in judging the policy issue. Some might contend that allowing individuals to carry a concealed weapon is a moral or cultural bad. Others might contend that greater liberty is a moral or cultural good. All we are confident in saying is that the evidence, such as it is, seems to support the hypothesis that the shall-issue law is generally beneficial with respect to its overall long run effect on crime.

Shall issue has its own set of variables. I mean this legislation is geared toward specific, vetted people. They are people with specific needs and are therefore the kind of people we know wouldn't be violent. This does not apply to the general statistics around concealed carry which results in all kinds of people owning guns even if they aren't convicted felons. The point in the abstract doesn't actually explain why these crime rates are lower.

Sorry, you are wrong.....

Again...27 years......we went from 4.7 million people with permits to carry guns to over 18.6 million people....and our gun murder rate went down 49%, our gun crime rate went down 75%...

You can't explain that...neither can she.....

Crime itself is down all over the nation and there are many factors for this. That's why it matters to do more localized research and look at the variables involved. Your national crime rate statistics can be attributed to myriad of reasons. You simply wanting to make it all about gun laws is dumb.

Wait a minute. You're the OP. It's you that's trying to make the case that the more guns, the more crime. Now that you've been challenged, all of a sudden, crime and murder rates are more than just about guns????

 

[Ray From Cleveland]

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

There are also measurable increases in murder charges filed in states after stand your ground laws are passed.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Here...actual research proving you wrong...

Okay again , the violent crime rates across the board have been going down. My study specifically makes the connection between gun ownership and GUN DEATHS SPECIFICALLY. Your so called studies are simply looking at crime trends that have already been going down anyway.

No...it doesn't.....it tries to link concealed carry to mass public shootings and I showed you how even the simplest question debunks the entire study on that point........

The study you found claims concealed carry gun permit numbers increase mass public shootings....I showed you that this is stupid and dumb as a claim...

You can't explain the link either...

Mass public shooters don't need a concealed carry permit to carry the gun to the place where they plan on committing mass murder.......

Criminals who can't legally buy, own or carry guns, can't get a legal carry permit to carry their already illegal gun.......and they are the ones committing almost all of the murder in this country in democrat party controlled cities...

Your study is crap.......

What the article says is that looser concealed carry laws contribute to more gun deaths in general - not just mass shootings. As a separate point, it says the good guy with a gun idea doesn’t affect mass shootings.

It can't prove that since making a connection between law abiding permit holders makes no sense...since the majority of all crime and gun murder is committed by people who can't legally have a gun permit for their already illegal guns.........

And I just posted other real studies showing that concealed carry, in fact, helps to reduce the crime rate......

Here is my request because I don't have the patience to read your wall post bullshit. Cite me ONE study, with a link, that shows in a given area, concealed carry reduced the crime rate in that specific area. Don't give me national crime statistics. I want crime statistics for a specific area.

“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.
Summary and Conclusion Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime. However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime. Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering. We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend. These results are very similar to those of Ayres and Donohue, properly interpreted. The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review. We acknowledge that, especially in light of the methodological issues of the literature in general, the magnitudes derived from our analysis of crime statistics and the supposed costs of crime might be dwarfed by other considerations in judging the policy issue. Some might contend that allowing individuals to carry a concealed weapon is a moral or cultural bad. Others might contend that greater liberty is a moral or cultural good. All we are confident in saying is that the evidence, such as it is, seems to support the hypothesis that the shall-issue law is generally beneficial with respect to its overall long run effect on crime.

Shall issue has its own set of variables. I mean this legislation is geared toward specific, vetted people. They are people with specific needs and are therefore the kind of people we know wouldn't be violent. This does not apply to the general statistics around concealed carry which results in all kinds of people owning guns even if they aren't convicted felons. The point in the abstract doesn't actually explain why these crime rates are lower.

Sorry, you are wrong.....

Again...27 years......we went from 4.7 million people with permits to carry guns to over 18.6 million people....and our gun murder rate went down 49%, our gun crime rate went down 75%...

You can't explain that...neither can she.....

Crime itself is down all over the nation and there are many factors for this. That's why it matters to do more localized research and look at the variables involved. Your national crime rate statistics can be attributed to myriad of reasons. You simply wanting to make it all about gun laws is dumb.

Wait a minute. You're the OP. It's you that's trying to make the case that the more guns, the more crime. Now that you've been challenged, all of a sudden, crime and murder rates are more than just about guns????

No, as I explained, my study controlled for variables that could contribute to a crime rate of a given area. It’s incredibly broad to make a correlation between the NATIONAL crime rate and gun ownership. There a myriad of factors as to why the national crime rate is declining. That’s why it’s important to look at a given area and control for confounding variables as the study
I posted did.

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

SHOW ME THE FUCKING RESEARCH OR FUCK OFF, YAHOO "NEWS"!!!

It’s linked in the article idiot.

No, it isn't as the article clearly states and I have shown. Increased gun ownership is far more likely to be a result of violent crime than the cause. I doubt you even bothered to read what you linked to and have no idea what it says. That's why I quoted it. But apparently you didn't bother to read that either.

A lot of things can be bi-directional. Studies suggest this for this reason. You have no good reason to actually believe that shit. Your confidence is based on nothing. Either way, nothing good comes from more higher gun ownership. Clearly people owning more guns doesn’t stop the crime rate anyway. The result is more bad people with guns.

Here...actual research proving you wrong...

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2). By comparison, Lott and Mustard found the concealed weapon dummy variable to be associated with a 7.65 percent reduction in total homicides across all counties and a 9 percent reduction in homicides when only large counties (populations of 100,000 or more) were included.43

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

Abstract: In an article published in 2011, Aneja, Donohue and Zhang found that shall-issue or right-to-carry (RTC) concealed weapons laws have no effect on any crime except for a positive effect on assault.

This paper reports a replication of their basic findings and some corresponding robustness checks, which reveal a serious omitted variable problem.

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

Okay again , the violent crime rates across the board have been going down. My study specifically makes the connection between gun ownership and GUN DEATHS SPECIFICALLY. Your so called studies are simply looking at crime trends that have already been going down anyway.

No...it doesn't.....it tries to link concealed carry to mass public shootings and I showed you how even the simplest question debunks the entire study on that point........

The study you found claims concealed carry gun permit numbers increase mass public shootings....I showed you that this is stupid and dumb as a claim...

You can't explain the link either...

Mass public shooters don't need a concealed carry permit to carry the gun to the place where they plan on committing mass murder.......

Criminals who can't legally buy, own or carry guns, can't get a legal carry permit to carry their already illegal gun.......and they are the ones committing almost all of the murder in this country in democrat party controlled cities...

Your study is crap.......

What the article says is that looser concealed carry laws contribute to more gun deaths in general - not just mass shootings. As a separate point, it says the good guy with a gun idea doesn’t affect mass shootings.

Concealed Permit Holder Stops Attempted Mass Shooting in Chicago

On Friday, an Uber driver with a concealed carry permit thwarted an attempted mass shooting by pulling his own weapon and shooting a gunman who had opened fire in Chicago's Logan Square.

Anecdotes don’t mean shit. You need to learn that.

It means a lot more than your studies. There have been similar cases, but nobody could prove the intent of the shooter was a mass murder because a CCW holder killed him.

Here is my request because I don't have the patience to read your wall post bullshit. Cite me ONE study, with a link, that shows in a given area, concealed carry reduced the crime rate in that specific area. Don't give me national crime statistics. I want crime statistics for a specific area.

And here....

CONCLUSION It is difficult to make a strong conclusion on the impact concealed carry permits have on crime because there are studies that show contradictory results. However, based on the thorough research conducted by John R. Lott (2003), the evidence from the case study in Dade County, and the research conducted by Kleck and Mertz (1995), it appears that benefits of allowing law abiding citizens to carry a concealed weapon outweigh the negatives that guns can bring upon a society. The concerns mentioned above against the policy are not substantiated by the evidence available. The evidence suggests that children are more likely to drown or die in a bicycle accident then they are to die from a loaded unlocked gun. In addition, private gun owners are far less likely to mistakenly kill someone then a police officer is (Lott Jr., 1998). Ultimately the policy appears to be effective in terms of crime reduction.

Right-to-Carry Concealed Weapon Laws and Homicide in Large U.S. Counties: The Effect on Weapon Types, Victim Characteristics, and Victim-Offender Relationships By DAVID E. OLSON AND MICHAEL D. MALTZ, Journal of Law and Economics, October 2001

Our results indicated that the direction of effect of the shall-issue law on total SHR homicide rates was similar to that obtained by Lott and Mustard, although the magnitude of the effect was somewhat smaller and was statistically significant at the 7 percent level. In our analysis, which included only counties with a 1977 population of 100,000 or more, laws allowing for concealed weapons were associated with a 6.52 percent reduction in total homicides (Table 2). By comparison, Lott and Mustard found the concealed weapon dummy variable to be associated with a 7.65 percent reduction in total homicides across all counties and a 9 percent reduction in homicides when only large counties (populations of 100,000 or more) were included.43

Confirming ìMore Guns, Less Crimeî Florenz Plassmann* & John Whitley**

CONCLUSION Analyzing county-level data for the entire United States from 1977 to 2000, we find annual reductions in murder rates between 1.5% and 2.3% for each additional year that a right-to-carry law is in effect.

For the first five years that such a law is in effect, the total benefit from reduced crimes usually ranges between about $2 and $3 billion per year.

The results are very similar to earlier estimates using county-level data from 1977 to 1996. We appreciate the continuing effort that Ayres and Donohue have made in discussing the impact of right-to-carry laws on crime rates. Yet we believe that both the new evidence provided by them as well as our new results show consistently that right-to-carry laws reduce crime and save lives. Unfortunately, a few simple mistakes lead Ayres and Donohue to incorrectly claim that crime rates significantly increase after right-to-carry laws are initially adopted and to misinterpret the significance of their own estimates that examined the year-to-year impact of the law.

~ The Impact of Right-to-Carry Laws on Crime: An Exercise in Replication1

Carlisle E. Moody College of William and Mary - Department of Economics, Virginia 23187, U.S.A. E-mail: [email protected] Thomas B. Marvell Justec Research, Virginia 23185, U.S.A. Paul R. Zimmerman U.S. Federal Trade Commission - Bureau of Economics, Washington, D.C., U.S.A. Fasil Alemante College of William and Mary, Virginia 23187, U.S.A.


Abstract: In an article published in 2011, Aneja, Donohue and Zhang found that shall-issue or right-to-carry (RTC) concealed weapons laws have no effect on any crime except for a positive effect on assault.

This paper reports a replication of their basic findings and some corresponding robustness checks, which reveal a serious omitted variable problem.

Once corrected for omitted variables, the most robust result, confirmed using both county and state data, is that RTC laws significantly reduce murder.

An examination of the effects of concealed weapons laws and assault weapons bans on state-level murder rates
Mark Gius

Abstract

The purpose of the present study is to determine the effects of state-level assault weapons bans and concealed weapons laws on state-level murder rates.

Using data for the period 1980 to 2009 and controlling for state and year fixed effects, the results of the present study suggest that states with restrictions on the carrying of concealed weapons had higher gun-related murder rates than other states.

It was also found that assault weapons bans did not significantly affect murder rates at the state level. These results suggest that restrictive concealed weapons laws may cause an increase in gun-related murders at the state level. The results of this study are consistent with some prior research in this area, most notably Lott and Mustard (1997).

“The Debate on Shall-Issue Laws” by Carlisle e. Moody and Thomas B. Marvell, published in Econ Journal Watch, volume 5, number 3, September 2008 It is also available here..


Summary and Conclusion

Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

However, the only way that they can produce the result that shall-issue laws increase crime is to confine the span of analysis to five years

. We show, using their own estimates, that if they had extended their analysis by one more year, they would have concluded that these laws reduce crime.

Since most states with shallissue laws have had these laws on the books for more than five years, and the law will presumably remain on the books for some time, the only relevant analysis extends beyond five years. We extend their analysis by adding three more years of data, control for the effects of crack cocaine, control for dynamic effects, and correct the standard errors for clustering.

We find that there is an initial increase in crime due to passage of the shall-issue law that is dwarfed over time by the decrease in crime associated with the post-law trend.

These results are very similar to those of Ayres and Donohue, properly interpreted.

The modified Ayres and Donohue model finds that shall-issue laws significantly reduce murder and burglary across all the adopting states. These laws appear to significantly increase assault, and have no net effect on rape, robbery, larceny, or auto theft. However, in the long run only the trend coefficients matter. We estimate a net benefit of $450 million per year as a result of the passage of these laws. We also estimate that, up through 2000, there was a cumulative overall net benefit of these laws of $28 billion since their passage. We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review

Abstract
“Shall-issue” laws require authorities to issue concealed-weapons permits to anyone who applies, unless the applicant has a criminal record or a history of mental illness. A large number of studies indicate that shall-issue laws reduce crime. Only one study, an influential paper in the Stanford Law Review (2003) by Ian Ayres and John J. Donohue iii, implies that these laws lead to an increase in crime. We apply an improved version of the Ayres and Donohue method to a more extensive data set. Our analysis, as well as Ayres and Donohue’s when projected beyond a five-year span, indicates that shall-issue laws decrease crime and the costs of crime. Purists in statistical analysis object with some cause to some of methods employed both by Ayres and Donohue and by us. But our paper upgrades Ayres and Donohue, so, until the next study comes along, our paper should neutralize Ayres and Donohue’s “more guns, more crime” conclusion.
Summary and Conclusion Many articles have been published finding that shall-issue laws reduce crime. Only one article, by Ayres and Donohue who employ a model that combines a dummy variable with a post-law trend, claims to find that shall-issue laws increase crime.

We think that there is credible statistical evidence that these laws lower the costs of crime. But at the very least, the present study should neutralize any “more guns, more crime” thinking based on Ayres and Donohue’s work in the Stanford Law Review. We acknowledge that, especially in light of the methodological issues of the literature in general, the magnitudes derived from our analysis of crime statistics and the supposed costs of crime might be dwarfed by other considerations in judging the policy issue. Some might contend that allowing individuals to carry a concealed weapon is a moral or cultural bad. Others might contend that greater liberty is a moral or cultural good. All we are confident in saying is that the evidence, such as it is, seems to support the hypothesis that the shall-issue law is generally beneficial with respect to its overall long run effect on crime.

Shall issue has its own set of variables. I mean this legislation is geared toward specific, vetted people. They are people with specific needs and are therefore the kind of people we know wouldn't be violent. This does not apply to the general statistics around concealed carry which results in all kinds of people owning guns even if they aren't convicted felons. The point in the abstract doesn't actually explain why these crime rates are lower.

Sorry, you are wrong.....

Again...27 years......we went from 4.7 million people with permits to carry guns to over 18.6 million people....and our gun murder rate went down 49%, our gun crime rate went down 75%...

You can't explain that...neither can she.....

Crime itself is down all over the nation and there are many factors for this. That's why it matters to do more localized research and look at the variables involved. Your national crime rate statistics can be attributed to myriad of reasons. You simply wanting to make it all about gun laws is dumb.

Wait a minute. You're the OP. It's you that's trying to make the case that the more guns, the more crime. Now that you've been challenged, all of a sudden, crime and murder rates are more than just about guns????

No, as I explained, my study controlled for variables that could contribute to a crime rate of a given area. It’s incredibly broad to make a correlation between the NATIONAL crime rate and gun ownership. There a myriad of factors as to why the national crime rate is declining. That’s why it’s important to look at a given area and control for confounding variables as the study
I posted did.

I read the OP. Unhappy with what I found, I went to the study itself. I admit, it was quite lengthy and I don't have the time to read it all right now, but I did read certain sections and scanned through the rest.

What I took note of is it mostly used the word Homicide and not Murder.

If I am attacked, use my gun to kill my attacker, I committed a homicide. Even when police arrive, find I did everything by the book, and the shooting was ruled justified. It's still a homicide, but it's not a murder. Big difference.

Homicide is the killing of another human being. Murder is a crime of intentionally killing another human being. Homicide is not a crime up to the point it's ruled a murder or manslaughter.

So what we have here is violent crime and gun crime going down, but homicides (in some places) going up. What doesn't sound kosher here?

What I was scanning for was some examples of their study: city vs city, county vs county, state vs state and so on. I found no such example.......not one. I wanted to measure the demographic changes, and the homicide rate vs murder rate. That would have been very telling.

Maybe you read the entire study and can tell me something I missed. If murder rates increased in X area, then homicides also increased, and we need to look at the economy during given years, the demographics, and other factors. However, if homicides increased, but the murder rate remained relatively the same, or perhaps even dropped like the rest of the country, then what that tells me is that lax CCW restrictions may be in play. CCW holders are killing the bad guys.

New research puts the 'good guy with a gun' idea to rest: Loose concealed-carry laws are linked to more firearm homicides

States with looser concealed-carry laws have higher rates of gun homicide. And higher gun-ownership rates are associated with more mass shootings.

www.yahoo.com

A new study found that states with looser concealed-carry gun laws have higher rates of gun homicide.

The results also showed that higher levels of gun ownership are associated with more mass shootings.

The study suggests the US could reduce gun violence by lowering levels of gun ownership and passing stricter concealed-carry laws.

Visit Business Insider's homepage for more stories.

The "good guy with a gun" theory goes like this: If more well-intentioned people carry guns, there's a higher chance of stopping a violent shooter.

Unfortunately, that's not how it works in real life, according to new research published in the journal Justice Quarterly. The study found that laws allowing more people to carry guns in public are associated with a rise in gun violence. The results also showed that the higher a state's gun-ownership rate, the more likely a mass shooting is.

There are also measurable increases in murder charges filed in states after stand your ground laws are passed.

What a load of crap.

The NRA has lost the support of the American people when Wayne LaPierre signed on with the gun manufacturers as a huckster and an arms dealer.

The NRA has attacked law enforcement and the FBI after NRA officials were co-opted by Russian agents and flew to Moscow to be entertained by Putin. They very investigated by the FBI after spending $30 million of Trump’s election, at a time when the organization was struggling financially.
