If a school with a massive bullying problem flat-out refuses to address the issue in spite of continued issues time after time, would parents be unjustified in getting upset at the school for not taking action? Should they be placated if the school just said "we are utterly disgusted and revolted by the bully's actions against your kids! But we also take a strong stance against punishing the bullies, because detention or expulsion would set a dangerous precedence that will eventually be abused"
