You need to watch a documentary on present-day Chicago.
I agree, it's amazing how all the guns and drugs get into that city when neither one is manufactured there.
Even more amazing is how the places they are manufactured don't seem to have those problems.
Because they don't pass them out there, they take the shit somewhere else to wreck havoc.
They're legally available for purchase there, whereas they are NOT in the areas about which you complain. Ergo, they are easier to obtain, yet there are fewer problems.
Now, as to your complaint that they "pass them out" to "wreck (sic) havoc", who are "they"? Surely you are talking about criminals who are not going to obey a mere law making what they are doing that is already illegal more so?
