SXSW Bully sucker punch. Justified or cheap?

No I agree with you, no rules in street fights. But first of all, there was absolutely no physical harm done to either of those 2 guys. The guy was picking for a fight yes, but I wouldn't say he deserved a sucker punch. You tell me why me knockout didn't start a fight with him when they were toe to toe? Why? Because he's a ***** and knew he'd get his *** whipped otherwise he'd have fought him and beat him down rather than take a cheap shot. He had no business interfering. None! He's no authority to anyone. He's some shmuck in a crowd deciding to show off.

You understand that there are no rules in street fights, but then you act like all fights must be 1 on 1. They rarely are, especially in a situation like this where it's likely your opponent has friends in the crowd. There's no ring/cage and no refs, no official sanctioning and no rules. If you pick a fight with one if my friends in the street, you better hope you have eyes in the back of your head because I will be circling around behind you and the last thing I'm thinking about is how I'm going to look in front of a bunch of strangers who I will never see again. I, like lots of people here, have seen these kind of things result in people getting killed or paralyzed or whatever. I'm not going to let that happen to someone I like in the name of honor or fairplay, it's just not going to happen. Call me a ***** if you want, but I am a stand-up guy with a lot of friends and I'll take that.
