106. Wasn't the former head of the FBI an extortionist, J Edgar Hoover i believe was his name....

Late in life and after his death Hoover became a controversial figure, as evidence of his secretive actions became known. His critics have accused him of exceeding the jurisdiction of the FBI.[1] He used the FBI to harass political dissenters and activists, to amass secret files on political leaders,[2] and to collect evidence using illegal methods.[3] Hoover consequently amassed a great deal of power and was in a position to intimidate and threaten sitting Presidents.[4] According to President Harry S Truman, Hoover transformed the FBI into his private secret police force; Truman stated that "we want no Gestapo or secret police. FBI is tending in that direction. They are dabbling in sex-life scandals and plain blackmail. J. Edgar Hoover would give his right eye to take over, and all congressmen and senators are afraid of him"

Most jurisdictions have statutes governing extortion that broaden the common-law definition. Under such statutes, any person who takes money or property from another by means of illegal compulsion may be guilty of the offense. When used in this sense, extortion is synonymous with blackmail, which is extortion by a private person. In addition, under some statutes a corporation may be liable for extortion

So what in the FBI's past would lead us to believe that conspiracy theory is true.
