you clearly dont know how criminals work
crimes of impulsive reaction will probably happen anyway, like stupid kids drunking their asses off and beating other people etc
criminals who are real criminals, that use crime as a way of living, survive, getting money etc, gun is almost like a work tool lol
if the guy knows there no guns in a house for example, is like a free pass, thats the real deal, impulsive shit will happens no matter what, humans are stupid
at least good citizens having guns they have a chance of defending themselfs, and the criminal will think better before jumping in
example: you hear a guy jumping in your house, you scream you have a gun and shot 1time (not in the guy, random bullet) the guy will 120% sure run away, thats it, gg
you are not killing people, but you are way more safe.
imagine you have young kid, wife, etc, think about it a little bit lol
