Hmm...well, given the fact that we live in a sue happy world, I figured that it'd be best to assess each situation and act accordingly. You are free to do as you choose, however, just understand that your actions may come back to haunt you. Hell, myself, I've posted that if faced with a weapon, ie: a mugging, that I'd rather not cooperate and instead, fight back immediately. Some have said that they'd rather cooperate, and then if they felt the badguy wasn't going to leave, but instead use the weapon, try to take them to another location, THEN they'd fight back. I disagree with that. But again, that situation is very different from the one described here. And before you or anyone else says it...no, I'm not saying the guy in this case didn't/wouldn't/couldn't have/use a weapon. I'm saying in the situation presented here, to chase the guy down, and bust him up, IMO, isnt warranted, but again, to each their own. Once again, I've said numerous times, to assess each situation and act accordingly. Would I bust the guy up? Sure, if, after I told the guy to **** off and leave me alone, he takes a swing at me, but again, we, as martial artists, should be able to control what we do, again, for each situation. If someone can't do that, then they've missed out on quite a bit in their training.
