No clue. I think the guy was really drunk and gone and just starting shit. The guy filming talks to the cops at the end and says he was in there and the guy asked him to sit with him, pulled out a sheriff's badge and wanted to question him for no reason. He refused, the guy ran to the counter - the video starts and all you hear is "You want to see my ASS!!!" and he goes crazy. Subway lady runs to the phone, he runs after her and rips it from the wall after jumping the counter. He gets back to the seating area, they close the fence and then chaos ensues. I think the two black kids only got involved because he was looking like he wanted to hurt the subway employees and they were both females.
Him whimpering when he gets tased is hilarious...lol...
