Because I don't think it's unreasonable to assume that Epstein would have had all the evidence he needed to bury every sex offender he ever entertained/supplied. He was also a man of significant means and, if his client list is as stacked with the worlds elite as has been made out, could absolutely make sure that in the event of his untimely death all the evidence is still released and they would burn along with him. As such the fact that nothing like that has come out since his death does make me wonder if his death was faked. You could argue it was far less risky for Epsteins clients to just get him out of the way whilst keeping him sweet. For people of that level of power it wouldn't be that difficult.
