The FBI special agent pool is lousy with white power fascists and Christian nationalists. Since its directorship isn't willing to clean house this is all a public relations front to suggest the FBI isn't as captured as it is.
But James Comey did it no favors, and even ushered in the MAGA era during which Trump ousted him.
You can expect about as much professionalism from the FBI as you can the DEA or ICE. And they all deserve capture and prosecuton by International nazi-hunters once the hounds are released from their slips.
