Oooooo, the profession has professional training and experience, and us mere mortals must defer to their judgement?

Bah. It's not true, not about cops, not about doctors, and not about teachers. Now I could be wrong here, but there have been no facts brought out to contradict my take as of yet. The teacher decided to stop the world because a girl was sulky and pissed him off. If her crimes were greater than that, show it. Sorry, I'm not willing to 'trust the teacher' and assume it.

In any case, let's be sure we understand that the criticism of the teacher is somewhat speculative, and more than anything a wish that he'd been able, him being who he was and the girl being who she was, to defuse instead of escalate the confrontation--before Officer Slam, the real and known bad actor, showed up and did his thing.
