Even if no public school teacher ever did a single thing wrong, the abuse of students *by other students* would be sufficient reason to shut them down. Why is it horrific for a 24-year-old teacher to sexually assault a student, but perfectly all right for a 17-year-old fellow student to do it?
She had been bullied [and sexually assaulted] by some of the students involved in the bullying.
Because of the bullying there are criminal charges against the students [4 girls and 2 boys, as I recall].
