Its nice to see a teacher getting at least suspended for bad behavior, but I recall with a surprising amount of bile the teachers who bullied me and my classmates when I was growing up. Its not as if people walking past couldn't hear Mr. Auwen flipping out and yelling at the kids. Its not like someone didn't already know the guy was a nutcase.
Having known school teachers, I know there's kids who will report problems just to be anti-authority or because they're angry about something else, but there was an institutional blindness to the whole thing that still very much disturbs me. I bet someone knew this guy was unstable and didn't say anything.
