I'm wondering if anyone has seen this video yet? YouTube - Fans Fight at US Open Tennis Djokovic vs. Petzschner [N0taBene] There doesn't seem to be much story behind what happened, but what I gather is that the younger guy is arguing about his seat with the older couple, and it turns nasty. Now I know this guy is being sort of a douche, but that doesn't mean that woman or that man can hit him. Same goes for the men who come by after his tussle with the older man. He might have been annoying but that still doesn't mean he can be assaulted.
