The indictment tells Stone he's going to prison if he doesn't cooperate. There's no reason for Mueller to reveal anything else publicly now.

The charges show that he can't be trusted to produce documents or devices voluntarily.

"Just because there's no evidence doesn't mean it's not true."

Don't have much use for faith in the unseen these days.

Why didn’t Mueller charge Stone with conspiracy? The rules in federal cases require that prosecutors provide defendants with broad discovery. By indicting Stone on a fairly narrow set of charges, Mueller limits what has to be disclosed & can protect ongoing investigation.

When he comes in for an interview they'll show him more damaging evidence that will have him exposed to serious time. Then he'll make a deal.
