I dont' know if the original poster's are reading this still, but here's my opinion: A #1- 90% of a success is to avoid the confrontation.."let me buy you beer" whatever calms the fool down. #2 - (This is probably what the original question was asking) If the fool decides "F-^* the beer" well here's where the switch gets flipped. I put myself in code RED..as he starts to come near or show other signs of aggression (never wait for the first punch) TAKE the first shot, let it be deadly, the throat, groin, temple, spine...whatever it takes. (Keep in mind, I never asked for this, I wanted to stop this long before it began) Also keep in mind, you don't know what this cat might know, maybe he's looking for your spine or throat. You might ask "how can you hit him in the spine if you’re facing him? Quick kick to the man-berries (Balls) he folds over then a deadly chop to the upper spine, behind the neck...GAME OVER. I live by the saying: "I'd rather be tried (Jury) by twelve than carried by six (pall bearers)"
