SXSW Bully sucker punch. Justified or cheap?

Could be because it was no one elses' business. If the two that were involved didn't want to at least try to take care of it, why was it this guy's business? The short answer-it wasn't-I hope he goes to jail.

I guess bullying is okay with you? I don't know how it'll stand legally, but personally, I think the guy got what he deserved.
