the rank and file of the FBI are probably dedicated professionals but the upper echelons are very dirty with politics. Same with the CIA and NSA
Given the power of these agencies, the temptation for abuse and political corruption is always there. Unfortunately under Holder, Lynch and Comey, they went off the rails.
The corrupt so-called agent “demoted” (believe me, he has NOT had his pay or grade decreased) to HR? Crap, they likely put him in charge of their CONTINUING campaign to recruit more leftists into the FBI.
