“How do they benefit from keeping it private?”
Some of the upper echelons of the FBI are probably on the list, and it’s great blackmail material for the politicians who are also on it.
The Clintons were involved, thus the FBI is corrupted. Democrats are openly sexual deviant, many republicans too are on that list. The world leaders and rich are exclusively on that list. It is a who’s who of the wealthy and politically elite.
Sounds possible... Epstein wanted 'the elites'. We know he pulled in the Clintons - and Billy and Hilly were right at 'the top'...
