SXSW Bully sucker punch. Justified or cheap?

El Caliente said
Have we found what caused the fight? What happened to lead up to this guy wanting to fight these two guys? The video is just clips and not the entire event.

You looking for the brand of beer that night? Or are you wondering what made this guy into a ****head in his youth?

You can't actually watch that video and think you're searching for what the other guys "did" to attract the bully right? C'mon dude.
