The point i'm trying to make is that it wasn't like this was some girl who was walking out of the stadium minding her own business and just got decked for no reason. The story I read about this says her and the group she came with were going at it with that guy, his friends, and the guys mother all game. At the end a fight broke out.
Instead of staying out of it she got herself involved in whatever was going on. So I don't feel that bad for her. The guys a jackass for hitting her. But this isn't some sweet innocent girl. She was clearly provoking him from what I can see in the video. My point is, stay out of trouble, and you won't find trouble. Her getting hit doesn't justify the way she chose to behave.
