For me the school system was like that.
Never had a talk with the principal, they just told my parents not to send me back. It was a shame because otherwise I liked that school. That kid was making threats against my life and I told the principal before that if he couldn't stop it I would protect myself.
The leadership and police were commonly complicit in these actions with the "boys will be boys, therefore no charges" actions. Attempting to bring lawsuits at that time was generally failure prone and put you at high risk of official oppression.
