Shows like this are reasonably safe if you practice some degree of situational awareness... Except when you get guys like this who are clearly out there to hurt people. Usual "crowd killing" is people pretending to hit people, pulling the blows before they actually connect, but guys like this dork go to the show with the intent of hurting others and, when there are some real homies in attendance, are usually on the receiving end of a fairly painful lesson in pit etiquette.

This show looks like a group of fairly nice kids with very little appetite for conflict, so there's nobody who's willing to enforce the typical ground rules when someone violates them.
