Imagine what this does for morale at the FBI. Not only is your director a putz, perhaps the worst director in history, but your work no longer matters. FBI agents aren't your corrupt local cops. They take (took) pride in being apolitical, professional investigators of the highest caliber.
Ever had your boss throw your hard work in the trash? This is that x10. Add to that the fear of professional or even legal consequences for investing the wrong person.
