Seven years? The FIBs have been a crooked unethical outfit starting with that old cross dresser Hoover. Look at how many of these criminals with badges were involved in the Whitey Bulger case.
I bet a diligent researcher with access to the Lexus/Nexus data base could write an encyclopedias worth of articles on these bums.
In the case of Bulger he was smarter then his FBI handlers. Instead of being recruited by the the FBI and manipulated. He allowed himself to be recruited and manipulated the FBI. Used the FBI to take down his criminal rivals. Not all criminals are drooling morons a few are indeed Professor Moriarty. Bulger was one such criminal.
