We both understand the concept that the US has more than 1 major social problem at the same time right and that other countries also have comparable levels of gang membership but wildly different murder rates.
So everyone who is currently killing each other with guns will see their enemy gang in the street and not decide to slash them because they are too lazy? They only wanted to shoot them?
It's the type of gangs in America, it's not about "gang membership" or whatever metric you're trying to throw out.
They shank people with tooth brushes in prison. MS-13 decapitates people with axes. It's the gangs, not the guns.
Chicago and many cities in America would be safer with more legal guns, less gangsters.
