Which is kinda the point. If I was driving to work and my damn prius broke down, my cell phone is dead and I tuck the 100 down in my shirt, while I am walking to the pay phone (if there is still such a thing) someone tries to take my stuff and elevates it when I tell him to beat it with some sort of force or deadly weapon, fire away, if you have no other recourse. This is really a very interesting topic we should all carefully consider before we carry a firearm in public, or even have one at home.
