I saw something similar on an AA flight from STI to JFK. A couple of guys in their mid 20s had more than they could handle and got rowdy with one of the stewardesses. They were sitting by the rear exit row and kept messing around with the door handles, and just being a pain in general.
Upon our arrival to JFK, there were about 10 NYC police officers in full riot gear waiting by the door as we exited the plane. I didn't look back, but I'm sure that they weren't there to exchange pleasantries with the 2 drunks at the back of the plane.
