We know for a fact that the FBI collected video evidence of what happened at the island. The girls, now women, have testified that they were trafficked. Ghislaine was convicted. I just can't see all that evidence and then think they don't know who the women were trafficked to.
So, i think they are hiding something. Its also well documented that Epstein was a Mossad agent. He had something like $600 mill in his bank account and no real track record of how he accumulated that wealth other than he worked at Bear Stearns. His time at Bear Stearns does not show that he would have made that kind of money.
It makes the most sense to me that Epstein was running a honeypot operation to compromise individuals.
I think the FBI ultimately got embarrassed that they were running such an operation, realizing they were abusing young women.
They thought they could control the narrative, but the invention of social media has jarred that control loose. And now the people are demanding answers.
