If Flynn withdrews his plea and the charges are dropped, then he should be able to sue the FBI and DOJ jackals who set him up with the perjury trap. Discovery will bring them all down, esp. if Flynn has any of his own notes (written immediately after the interview) or there is any tape-recording/wiretap record of it.
Conviction of the two FBI agents who interviewed him (Strzok is already in very deep crap) would unravel the whole setup and scandal, bringing down everyone we have come to “love and hate”.
We could have our own Bastille Day celebration if this is done by July 15th. Viva la Guillotine!
For Flynn, exoneration isn't good enough. He has to be exonerated in a way that allows him to collect a huge financial settlement from the perpetrators of this disaster.
