I don't dispute that students attack teachers, and I'm sure it happens more often than the other way around since people only get uppity about teachers attacking students (for various reasons, some legitimate).

But the episode basically implied that every student turned every incident with a teacher around into an accusation that the teacher had attacked the student. I find it incredibly hard to believe that all the teachers in New York's rubber room are there for no reason (although the whole rubber room procedure is archaic). Even the teacher who eventually went on a killing spree was described as "a good teacher" who "snapped" (whereas when they thought it was a student planning the killing spree, it was all about the kid either being suicidal-depressive or psychotic). I found that explanation way too simplistic. I don't disagree with anything you're saying, but I'm really responding more to the episode.
