All of those questions are matters of prosecutorial discretion, with huge latitude.

But given your experience & observations, what are your best guesstimates on such?

"By the book," the person taking the deal has to cooperate as a witness.

I figure the Sessions DOJ will go by the book. McCabe won't have to rat anybody out, menaing no need to disclose who the other players are. But he has to make himself available for questioning, as does ANY CITIZEN. The 5th amendment as to the conduct he is charged with is out the window.

You've used up your three questions.
