That one is for the Sarah Brady-types who tell you "you shouldn't have a gun because someone could hurt you with it."
This is true -- someone could hurt you with it, but only after you have achieved slide-lock on an empty magazine. And if you have mastered proper weapon skills, there should be 7 ventilated bad-guys, so the only bad-guys left who can hurt you are numbers 8 and up (this assumes you have mastered the Colt M1911).
