SXSW Bully sucker punch. Justified or cheap?

He played no game. I guess it'd be ok if I went up to anyone fighting and sucker punched when I had no business interfering with it right? I don't put myself in bs and I've had my share of fighting. I'm sure most you would be in the crowd watching this type of behavior. I have no qualms with fighting. I could careless if one kills the other. It's none of my business what takes place. But I know cheap shots when I see them.

Most people are able to distinguish between prize fighting and street fighting. During prize fights, cheap shots, sucker punching, bum rushing, fish hooking, eye gouging, ear biting... Yes, against the rules as well as very poor sportsmanship, John Wayne would not approve. But all that stuff is to be expected in the streets. There, the ends always justify the means.
