You might be right. But they made a deal with Sammy the Bull. SO who knows?
I don’t think there were or are any deals being offered to Epstein other than maybe he gets to pick one of two cellmates.
Instead of ‘witness protection’ I’m thinking more along the lines of ‘protective custody’. i.e. we’ll keep you alive through the trial.
If he hasn’t assumed room temperature.
Either way, the evidence is now entered into the court system. That’s a LOT.
