Thomas J Baker had a legendary career in the FBI. For example, "as the Assistant Special Agent in Charge of the FBI Washington Field Office, he was one of the first agents on the scene of President Reagan’s shooting; Tom directed the FBI’s initial response to that crisis." (That's from his web page, linked below.)
He loves the organization and is thus frustrated, angry, and saddened to see "a once-great agency become a threat to Democracy" which happens to be the subtitle of his new book, "The Fall of the FBI."
