The video clearly shows someone get viciously attacked from behind, she didn't see it coming.
That alone is bad enough, and a crime. So yeah, arrest and expulsion are in order.
But that's all you got. The rest are details you decided to frame it in, and like the other videos you cited that you post, take an "Us vs Them" approach.
You're not posting about crimes - otherwise you'd be posting thousands a day - you posting to suit and push an adversarial agenda.
Wait, I just saw, you didn't have fights in school? A nun - yes, NUN, pulled my hair from behind when we were going down the steps in line in 7th grade, my homeroom teacher. Back and forth, saying, "You. like. pulling. people's. hair?" She stopped when 2 girls at the back yelled, "Not THAT Modda, the OTHER Modda!" (yes, there were 2 of us who shared the same name). The Sister stop, said, "Oh, I'm sorry," and that was that.
No trans involved.
