The teacher apparently thought he was physically threatening a female classmate. I can't say the response was appropriate, but I can't say I'd disapprove if that was the situation.

Funny enough though, teachers used to be (and still are in some places) privileged against battery suits in the event they were battering the student because that student was a disruption in the classroom. It does sound like that kid and maybe some others there would benefit from a good paddling.
