I googled for other clips and this one is a pretty clear clip (good focus).
It almost looks like the shooter actually grabs a tied headband because the girls hair can be seen in what looks to be a pony tail that flops away as she is pulled to the floor. Either way doesn't matter in that clip she is clearly jerked to the floor from something on her head being pulled and it is blatantly flagrant.
I would like to see extended video of the elbow mentioned earlier but couldn't find it.
