Re: So WTF is wrong with the US school system?
Bullying and abuse by staff is accepted.
At Columbine the sports 'jocks' even got away with rape because the staff persuaded the police to ignore them.
In this case the kid wasn't good at sports so the sports staff bullied and abused him giving the green light for other pupils to do the same.
It has been noted that he didn't shoot at pupils he liked.
