"Watch the video. The teacher shouted but I don't think he was out of line. The kids were grinning and slumping in their chairs. The "pulling the chair from under the kid" thing wasn't caught on video. My sympathies are so with the teacher on this one."
What's wrong with a little yelling? I can't imagine, sitting slumped in my chair with the National Anthem playing, and not inviting some response from the teacher. THis is his turf, not the student's. They basically were there not to learn but to desrupt.

It is clearly visible on the bottom left of the video that the teacher has his hand firmly on the back of the student's chair.
