So, basically he was under investigation, they didn’t let him know that he was under investigation, they didn’t advise him of his Miranda Warnings and they interviewed him, under those circumstances anyway. Hmmmmmmm..... in REAL law enforcement investigations this is called, The Fruit From The Poisonous Tree. And everything obtained from it should be tossed. But, this is the FBI(Famous But Incompetent) and the DOJ at its most corrupt, so none of those rules matter.
However, the General should have been smarter than to talk to a bunch of flat foot FBI weenies who didn’t have the clearance to know what he knew and did.
And he should have disclosed that he was working as an agent for another county. It is somewhat a shame that conservatives forget this detail....but it is a pretty big deal.
That said, Comey/McCabe and the rest of the traitors working for Obama should be facing a firing squad.
You don't expect a crowd that's the same as back-shooting Taliban Muzzies to be disguised as American fibbie agents...
When the FBI shows up and starts asking you about your actions a prudent person might conclude that he was under investigation.
Further, Miranda warnings are for people in custody, not officials sitting in the White House sitting for a voluntary interview.
The FBI's behavior was routine and the same as takes place with every law enforcement agency at every level in America.
They may have been more successful than they often are but that's due to a combination of disorganization and arrogance on the part of the Administration and Flynn, not unethical FBI behavior.
