PntBall - I wouldn't have thought that, in America where gun ownership is so rife, your aggressor would be carrying a knife. If there is a chance of someone having superior weapons to you, you would get yourself have equal standing, surely? Heh, kind of the story of the world really.

Roog - Very fair point. I bow to your intelligent thinking! _O_

TX - aaahhh sorry I misunderstood what you meant. Its all to do with the potential threat of a gun. Whether empty or full, the aggressor is faced with a gun. I get you now. _O_
