If Trump doesn’t pardon General Flynn then I hope he petitions for the courts to overturn the conviction.
A pardon is the right remedy. Then General Flynn needs to sue the perps, asserting that they acted so far outside the scope of their employment so as to make them personally liable. There are some deep pockets there, Comey is a multimillionaire.
The hard part will be getting past their government immunity. It can be done if their conduct is found sufficiently egregious. Just a matter of finding the right judge.
One encouraging sign on that is the sentencing date date has been moved back at least two times. Now that the current issue is exposed it’s time to go after a copy of the unredacted FISA application. Also in that vain the verbal super secret delineation re scope of Mueller’s coverage and basis of investigation areas should be demurred. This is merely part and parcel of covering what has actually taken place from the witch hunts inception until now.
