Yes.do you think there is any chance in hell that mueller would allow flynn to plea away conspiring with the russians for a no time charge of lying to the fbi and fara?
That is exactly the way good prosecutors work a plea bargain, with a person who has useful info on another bigger criminal
It's the basic nature of how plea bargains work.
If Mueller had Flynn nailed for -only- lying, and Flynn saw no hope of beating the rap, what does he gain by pleading guilty? He saw enough of Mueller's cards to realize that he was going to get nailed for something much worse if he didn't cooperate. Also, he did not have a "no-time charge" as he did not get any sentencing guarantee and that charge can definitely land one in the big house
Add to the above: this is exactly how Mueller has operated in the past on high-value, difficult-to-nail prosecutions.
