A number of years ago, when I lived in KC, I caught a prowler (window peeper) hiding in some bushes by my house. My car headlights and yelling at him were enough to scare him away however, I have wondered what would have happened if he "jumped me". Guess this is a question that can only be answered in the split seconds when it happens.
