I don't know if she is dead in the mug shot but this shit looks pretty convincing that the cop broke her ribs and she died because of that. Thats a guess though.
I just watched the full video on youtube, what happened was that the cop told her to get out of the car and ofcourse she refused. He then tells her another 20 times and she refuses pulling up the you have no right shit. Then he pulls out his taser which is kinda stupid of him to make her get out. He only tells her to get out because maybe he thought she was a bit edgy, well thats what I thought. I know one thing though, that it was a retard move for him to pull his taser.
