Perhaps so. However, I "choose" not to carry anything more dangerous than a Swiss Army knife, and cringe whenever I see my alleged civilian "protectors" walking around with a gun holstered on their hips.   Where I live, concealed carry requires a minimum of training, but carrying a gun openly doesn't. I cringe at the thought of these bozos blazing away in my vicinity at some miscreant.

We recently had an incident here in Albuquerque in which a guy caught someone trying to hotwire his car in the middle of the night. He pulled his gun and ran him off..ok so far. He then chased him for two blocks, over a fence, into an arroyo, and shot him dead because he "assumed a threatening stance". He was convicted of manslaughter, sentenced to (I think) 3 years in jail and to pay the criminal's family (again, I think) $500 a month for 5 years. There is a very vocal movement for a full pardon - let the bugger rot.
