I learned late in life something that disturbed me at the time... my SO made a statement,,, in a fight you fight to win, no holds barred and no games. or YOU could be DEAD. I spent alot of time thinking about that and it finally got thru to me that that is the absolute truth in a dangerous situation. I had a prob on one hand knowing he carries several highly ranked martial arts belts, but when you get right down to it, a person is committing a crime? Stop it hpwever you can with whatever means needed. If they run... stop them for the police to haul off. But don't do more than you need (IF you can restrain yourself) to hold them still.
Shame you allowed your gun rights to be taken away Aussie. You guys need to get some new laws passed!!
