There's a video in the Guns thread, I think, of just such an action. They go in with, if I remember correctly, a shotgun, and come out with several more guns and whatever was in the register. Ballsy move, but had the clerk been armed, and proper security measures been followed, it would never have happened.
The doughnut shop example still stands, though.
That's the idea. Though the events will still happen, if the assailants are desperate enough, and when they do, they'll be bloodier, that very bloodiness will deter most of them from happening in the first place. Reducing the level of desperation in the society is important too (but isn't really relevant to a gun control discussion).
Well, no, the doughnut example won't stand either I'm afraid.

Have you ever had anything to do with criminals? I don't mean victimized, but worked with them? I have, by association, done that. They are not generally deterred by consequences, since few of them plan that far, or if they do they are convinced that they will come out on top. The assault will be bloodier, and that's about it. Best case nobody is seriously hurt. Worst case someone lost a son/daughter/father/mother.
