APP.COM - Video of teacher's outburst is on Web

This story should ring to true to anyone who's had a teacher like this. I'm torn: on one hand, I think this teacher is totally out of line yelling at his students like that. He gains nothing by sacrificing all the inherent respect his position commands. On the other hand, those kids were asking for it, showing no respect at all to their teacher (screw the anthem). the video is here.
