should have pressed charges, if you used your valid ID to get in, but somehow ended up with 21+ vip passes and drinks. Not your fault, clubs fault to improperly check ID, allowing a underage to drink then using unnecessary force when you were not resisting. Yea the club got money, but if you have good enough lawyer the club will mostly likely try to settle it. All cops are hired by the clubs, and are pretty much working for them if they are standing infront of it. Public means shit to them then.

Edit saw it was opera. Didn't have a bad experience there, but they everyone from owner to bouncers aren't afraid to show power.
