I read this morning that Acosta said he was waved off of harsh prosecution because Epstein was 'intell'. In which case, JE may have been giving his blackmail tapes to FBI or CIA. Who knows how they may have used them.
I agree that Acosta was likely waived off of harsh prosecution. I doubt it was for "intel." That was probably their cover story. It was more likely that it was for "coverup." One or more of the political ruling class (i.e.: DEEP STATE) was implicated, and I am positive Epstein's lawyers relayed in info that he had a dead man's switch rigged and that people were going down. That's the ONLY thing that makes sense to me (that he got that sweet deal without giving up co-conspirators).
