Public school administrators are awful. The assistant principal wanted to suspend my son (and just give detention to the bully).
Eventually, got the principal involved and his football coach was in there too. That and a threat to call the local media. Ultimately, we agreed that son would have an extra assignment from class.
While I think son partially had good intentions at heart, he doesn't like the bully so I think there was a dual purpose to him telling the bully that.
Obviously, son being starting safety/punter on football team didnt hurt either when getting punishment reduced.
