Thoughts?

If you haven't seen this video, basically this student was being extremely disobedient and disrespectful. When he got into the teacher's face, the teacher put his hands on the student's chest to keep him from getting closer. The student reached for something to strike the teacher with, and the teacher quickly disarmed him. After that the student tried to tackle the teacher and went on to throw punches. The teacher never once hit the student, just kept trying to keep the student in a position where he couldn't move.

I'm curious as to what everyone's stand point is on this.
