If a mid-level scumbag involved with the mob "kills himself," in his cell before testifying, how many people have trouble believing it was a mob hit?
That is talking about people of little to no importance. Epstein was many things, but he wasn't insignificant...

The evidence can never be certain, because a hit and suicide would look exactly the same, and there are means & motive in either case.
But to just outright dismiss murder as "conspiracy theory" is real confabulatory gymnastics.
