More frivolous laws? Criminals love the idea of more frivolous gun laws...
Yes gun laws like in countries where they don't have mass shootings. I hardly call that frivolous.
Do they have drugs in those unnamed countries? Drugs are illegal here and we have lots of drugs. You want drugs and don't know where to get them? Ask a high schooler, they'll get them for you
Lets name some countries Denmark, UK, Germany, France, Japan.... We have whole countries where gun control is working. We also made machine gun heavily regulated and they have pretty much disappeared from crime.
OK, good. At least a start. Now tell me why your single cause leads to that result in all those countries, they have fewer shootings because they have more gun laws.
Don't forget to include why we didn't have those shootings either other than the last 20-30 years and we had the same number of guns
Also keep in mind the types of guns have really changed. 30 years ago everyone didn't have high capacity magazines. Now we are littered with them. When I was a kid cops were still using revolvers. Flood a country with guns for mass killing and you get more mass killing. We had the sense to heavily regulate machine guns.
There were far fewer shootings. All your argument boils down to is putting the genie back in the bottle. The trend at all the places that you mentioned is the same as here. You're trying to swim upstream with no indication it will work.
And in fact, shooting after shooting is showing why that is evil, it IS working to disarm honest citizens. How do you look at 17 dead and not think oh your God, maybe some people need to be armed? Where is your soul, man?
