I don’t think Trump should pardon Flynn.
For Flynn to accept the pardon would mean Flynn accepts the crime he’s been charged with.
Make the FBI admit under oath in court that the dog ate their homework.
Make the FBI name EVERYONE in the chain of custody under oath.
Strip EVERYONE in that chain of custody of their Sovereign Immunity protections.
Make Flynn whole by making everyone who maliciously and deliberately persecuted him whether they are in the named chain of custody or in any way active in that persecution by other acts, financially and personally responsible for every penny in damages they caused him, plus whatever penalties the Court may see fit to impose (Treble damages? More?)
That works for me!
