This could get interesting.

I’m confident it will become clear that he was/is a rat, scumbag, unethical sob, etc. But none of that is criminal. Lying isn’t a crime unless you do it under oath or to obstruct. Etc. He did all kinds of evil stuff but unless there is a solid legal case to he made, his punishment may not come in this life. Plus, his job gave him a lot of wiggle-room.
Maybe in time some of the people who have really been hurt by this hoax can go after some of these lying creeps civilly.
