In Alberta in Canada in the early 80's it was quite normal to see a truck or 2 pulled up outside a bar, unlocked, keys in the ignition and a rack of rifles, sometimes as many as 5 or 6, behind the seats, And the owners in the bar drinking beer and more. no one paid it any attention. But there was never any gunfights or shoot-ups.
Which I suppose goes to suggest it's not the guns its the idiots holding them.
