She and Epstein no doubt distributed to several trusted “custodians” professionally prepared documented packages (names, dates, locations, travel itineraries, credible witnesses, videos and DNA samples, to name a few) for publication in the event of her untimely demise.
The most that buys here is a comfortable incarceration. It doesn’t even shorten her sentence. Her problem is that she’ll never be allowed to testify behind any of that evidence you mention. She’ll end up dead first. And if the stuff comes out after she’s dead — well then it’s just fodder for the people that write history — because the provenance of those documents will be in dispute.
That may be all she bargains for, at least initially. She may not wish to be on the streets anywhere on the globe. It is most certainly not just the powerful she fears.
Apart from any issue as to the content and quality of her evidence, she may prefer a room in a federally managed country club that offers a decent chance she will not hang herself.
But then, we are just talking predictions, right?
