This Is The Dumbest Thing Ever

Rich Lowry, writing at the New York Post, argues that Epstein could not have been a Mossad asset because "[c]learly, it would risk an enormous black eye for the state of Israel to connect itself to a known sex offender whose lifestyle was a flamboyant and ongoing crime scene." Almost as big of a black eye if Israel employed a spy to steal the National Security Agency's ten-volume manual on how the U.S. gathers its signal intelligence, and disclosed the names of thousands of people who had cooperated with U.S. intelligence agencies; blackmailed President Clinton into releasing the aforementioned spy from prison; used influential Jewish entrepreneurs to spy on the U.S.;  and established an espionage network in the U.S. (including the "dancing Jews" that were briefly investigated after the 9/11 attacks and subsequently fled back to Israel). Moreover, there are witnesses that say otherwise. In addition to the allegation that the U.S. Attorney in Florida giving Epstein a plea deal because Epstein was with intelligence, Wikipedia notes (footnotes omitted):

The US journalists Dylan Howard, Melissa Cronin and James Robertson linked the Mossad to American sex offender Jeffrey Epstein in their book Epstein: Dead Men Tell No Tales. They relied for the most part on the former Israeli intelligence officer Ari Ben-Menashe. According to him, Epstein's activities as a spy served to gather compromising material on powerful people in order to blackmail them. There is also a possible connection to the Mossad via Ghislaine Maxwell, whose father Robert Maxwell is said to have had contacts with the Mossad. Epstein's victim Virginia Giuffre also alleged Epstein to be an intelligence asset, linking on Twitter to a Reddit page, that alleged Epstein being a spy, running a blackmail operation.   

No, Epstein's flamboyant lifestyle made him a good candidate to use as a spy. His life as an "ongoing crime scene" merely turned him into a liability should he decide to talk in order to avoid prosecution. Unfortunately we will probably never know: Epstein is dead and it is very likely that incriminating documents and video have been destroyed or dropped into an even bigger black hole.
