He got arrested, he'll have criminal charges pressed against him, and the couple will file a civil suit to get some money out of em. Nobody threw a chair back, he threw a chair and that's about all that happened. Security didn't really do shit cuz they didn't know it was gonna happen, dude did that shit out of nowhere for no reason, the fans weren't cussin at him or really talkin shit or nothin so nobody expected anything to happen.
