I totally agree! I carry, and the reason I do is not only to protect myself, but anyone in danger around me as well.
As far as having to utilise it, yes, I will do so to stop a threat. Coming from a family with a heavy law enforcement and military background, I am comfortable with carrying. I liked the story above with the cop asking "what are you afraid of... Absolutely nothing." Sounds like me.
Case in point... Tonight here in Houston, there was a "smash and grab" of a major gun store here. Several guns were stolen, and the criminals are still at large. Like my dad always says, "with hope that you never have to pull your weapon, if you do, you better be prepared to use it." Guns are getting into the wrong hands these days, and with these cases of people having no value for life and nothing to lose, (walking into office parties, stores, restaurants, etc.), at least I am always prepared for the worst, and willing to protect myself, or defend someone in danger. It has nothing to do with being scared. A 40 calibre has much more power to do damage than any type of martial arts, or moves.
