"Guns for Beginners: Three Ways to Lose a Gunfight"

An article from The Truth About Guns. The three ways:

1. Pick the wrong fight--i.e., being in a stupid place, with stupid people, doing stupid things; or not getting away when you had a chance.
2. Fail to draw your gun in time--i.e., delaying deployment of your weapon when you do need it; or, since you will likely be reacting to someone else's hostile actions, attempting to shoot before moving off the X.
3. Assume the bad guy will stop when they're shot.
