He's got her exactly where he wants her, which is beholden to his largesse. She gets out of line, he snaps his fingers and she's in a supermax. Plus he has way more control over her communications from a prison than if she's walking around. Plus the world at large takes words from people in prison less seriously, unless they're like MLK.

Conversely, what's the benefit to him to let her go free? Not even his cultists will be a fan of THAT move.

Help me understand what I'm missing, if I indeed am?

To start, I don't feel strongly about it at all. If logic had any part in the decision making he and Blanche would have left that filth in the hole she was in to begin with. Right now, they're at a stalemate. She has information, not just of the Felon but also those that he's keeping in his back pocket.

Blanche "interviewed" her not only to see what information she has but also the proof. Also, they want to know if she has a fail-safe in place in the event of her untimely death which I would be willing to bet, she does. Otherwise, why hasn't she met with her demise. And why would they have made the change of her housing and rewarded her? They knew there would be backlash and not just from Democrats. The only logic in that is she's a threat.

...but will run like a scared puppy to hide from reporters when in happens.

to get her out of the country. And fuck Blanche.

And he will do it willingly.

If she is released by commutation and/or pardon, street justice will take care of her. We know now the Epstein files have global implications of sexual abusers. I don’t think she is safe outside of prison.

She'd retreat to the UK and a semi-anonymous life as an heiress. No one's "street justicing" someone who won't be on the street.
