defense, in the US, and you are all worried about your "sniper' rifle, your hunting rifle, your AK, your smg, your "combat" shotgun.
That's 100 a day who DO have to actually shoot somebody(or some animal) in self defense. How many have you ever even HEARD of who actually NEEDED a rifle? In practically every case, if they had a lick of sense (like Koresh's people, The Order, Weaver, etc, they would have KNOWN that a confrontation with The Man was inevitable, and just been ELSEWHERE by the time that The Man came calling. Ergo, NO need of the rifle.
