Not where I live. Only sworn law enforcement (peace officers and police) have justification to use force in that manner. Else it's the crime of assault (that's what it's called here; battery is a civil tort).
No one seems to notice, but what was the guy forcibly "arrested" for? Is there a "laser pointer at concert" law where this happened? What would he have been charged with? Even if the "security" were really off duty police, you need a crime to make a lawful arrest. What was it, the catch all disorderly conduct?
I wouldn't be caught dead at one of these circuses anyway so I'm good with the cops ripping someone's head off, but let's have a crime and a cop to justify it. This just looks like typical thug entourage with no training. Aggravated assault, unlawful restraint and if they moved him, kidnapping. The thug security can go to jail to visit their buddies and earn more street cred.
