@chai2,
here's something else to think about...
the good thing about guns, is they make a lot of noise.
other people are gonna know that a gun went off, and wonder what's up*
*(unless you are the unlucky victim of a professional assassin, or a crazy gun nut with a silencer)
some nut-job can taze you, and all that other folks will hear is your body floppin' around like a fish...
