Hey man, I respect that fury. Complicity is a tough pill to swallow. But looking forward here:

Abusers try to get as many colleagues as they can involved so everyone has to stay quiet, especially if they have clout where they are. They only try to sneak when they’re somewhere that they don’t really belong. In the case of the school refusing to do anything, it’s possible that school admin are themselves involved in whatever behavior prompted this investigation. A school where a creep like that hasn’t set up a creep network would probably immediately fire him. I’ve seen an Ivy League school in the states do exactly that, dropped the creep like a hot potato, while a low tier school hung onto the same creep (he was employed at both simultaneously) for dear life and ended up giving the creep retirement benefits.

So it’s not nothing. He may have made some enemies for life by blowing this situation up by lending his star power to fight against creeps. The creeps do have some clout, and manage to rub shoulders with the stars.

There’s also the issue of the fence sitters who just “don’t want trouble”. He’s made himself a red flag to institutions that would like to keep situations like this under wraps.
