Don Firth brings up a subject that is pertinent. Why use a gun? Why keep a gun for protection? In an emergency, a fired gun is expected to be the ultimate answer- a case of applying capital punishment whether or not it was a capital offense.

There is no recource to a fired gun.

Why not use a temporary disabler? Why not a Taser or a Mace or any of a number of other things that are meant to stop an offender in his/her tracks?
