I don't know if Preston has a case because I'm no lawyer but I'm guessing that
@FROG's demanding a "deep dive" from his followers (did he say WarCampaign by name?) into Preston followed by his mod/WarCampaign member/prostitute/dox monkey producing the porn then Ethan disseminating and encouraging the dissemination of said porn for the express purpose of humiliating Poulter and finally the statement that Poulter was destroyed for fucking with CG. That led to the
alleged criminal investigation of Ethan.
(Edit: I can't believe he was stupid enough to do all of that publicly)
I believe that it's the sexual nature of the humiliation that makes it illegal and it's the perverted nature of the fetish/"sexual orientation" that might make it a "hate crime" which is horse shit.
Whether there is an actual prosecutable case there is up to a DA to decide but if the police are investigating and Preston gets access to the info unearthed in the investigation through FOIA or otherwise Ethan could be in a world of hurt.
If cops pull back the curtain and find anything else that's illegal when they're looking at the gay ops we all know happened things could get real interesting.
