And yes, I've been in that situation. And no, I didn't shoot. (Richmond, VA circa 1990)

Okay. You are assuming that "bad guys" will do what you tell them if you point a gun at them. I can tell you(as a law enforcement officer) that is a bad assumption. If the "bad guy" thinks you will NOT shoot, or KNOWS that you can't legally shoot he will NOT comply with anything you say, but will most likely walk away or laugh at you.
