You bet it does.
My sister used to work in a restraunt/bar in Oregon. They allow folks to carry guns there, but when entering a bar they have to check them in if they are headed for the bar. They had no trouble with fights, robberies or general rough behavior because ALL the patrons knew full well that if trouble broke out the bar keep would hand out the guns to the owners, pickup one themselves or give one to the bouncer. No one was stupid enough to test the system. (This was in cattle/ranch country and everyone used guns.)
And they taught their kids how to handle them, why they were dangerous and what they could do. Toddlers knew better than to touch a gun or play with one because they were exposed to the realities of hunting as part of the way they lived and ate. No one let their kids play with the darn things, but they sure taught them that they killed and were not toys in the first place.
In countries where the citizens are not allowed to be armed they actually have more murders which are carried out using rocks, knives and other weapons like pipes and tree branches, or beatings. Guns are not the problem. People are.
