There's a scene in the 1979 film Scum (https://www.imdb.com/title/tt0079871/?ref_=nv_sr_srsg_0) where one of the warders in a young offenders' institution allows a bullied inmate to be framed by his peers and punishes him.

When I saw that (not long after it was released) I thought how well that captured the spirit of many school interactions, where bullies would blame their victim and the teachers would fall for it.

Yup, I was a bully in high school and when my victim went and complained about it to the math teacher, the teacher went and humiliated him in front of the whole class. Felt good at the time...
