Does that even exist? How do you know? How do you release something that doesn't exist?
"The Epstein client list" is a metonymy, like "The White House announced today that it has no clue what the hell is going on." The White House cannot
literally announce anything. Likewise, "the client list" is a metonymous reference to the evidence against the rich and powerful which had been collected by Epstein. It is possible that all that evidence was cleaned out or destroyed before the FBI got there.
People like Epstein have a huge, full-time support team whose jobs are to manage each and every detail of their lives, including things like "if my lawyer calls and tells you the Pineapple Is Rotten, you push this button right here next to the server rack labeled 'Rotten Pineapple'." Hard-drives + thermite = no data. Or whatever. Since the prevailing hypothesis is that Epstein was CIA/Mossad connected (likely both), whatever digital setup he had on the island would likely have been national-security grade.
Whether it was deleted then and there, or later destroyed, the likelihood that any of the evidence of crimes committed on that island survived past 2008 (except for Epstein's own crimes) is practically zero. The impetus to destroy that dirt would have been practically infinite. That such dirt must have existed at one point can be inferred from the billowing smoke surrounding the entire Epstein story -- watch any interview of Whitney Webb to get up to speed on the literal mountain of "coincidental" evidence surrounding Epstein and his network. A few coincidences over a lifetime might be mere coincidences. But a literal category-5 hurricane of coincidences are not coincidences any more, they are actual evidence that something fishy is going on, and being covered up. As Webb has explained in detail, Epstein's primary "job" was likely money laundering, not sex-trafficking. But the overlap between dirty money, and dirt-itself, should be obvious.
One of the things that makes drugs so valuable in the underworld is that you can rat somebody out to the cops for giving you a briefcase of cash (and keep almost all the cash and just lie about it!), but you can't rat them out if they paid you in drugs because you, too, are now guilty of a crime. So, moving dirty money is intimately involved with crime because the payer and payee need to be "equally dirty" in order for the exchange to be secure against one side ratting the other out. It appears that the trafficking, in part, served this function and its existence was largely ancillary to the real business going on. So, the coverup of whatever crimes involving minors were going on on that island, is nothing compared to the cover-up of the money laundering which was surely funneling through Epstein island. And note that the DC kid-diddlers have successfully managed to make this a story
exclusively about crimes against minors, not money laundering! So, the "disclosure" itself is a cover-up!!
