*Robert Kennedy
When Robert Kennedy became Attorney General in 1961, he found FBI chief J. Edgar Hoover uncooperative with his anti-crime campaign, so he formed his own intelligence unit, initiating massive illegal wire-tap operations against James Hoffa, Carlos Marcello and other mobsters, and other political enemies such as State Department Security Evaluator Otto Otepka, who had rejected several Kennedy appointments as security risks. Although Robert Kennedy had once worked for Senator Joseph McCarthy and Otepka assisted the McCarthy-inspired Senate Subcommittee on Internal Security, in mid-1963 Otepka was suddenly moved to a less sensitive post, and his safe was drilled open. Inside was found a study on American defectors to the U.S.S.R., including Lee Harvey Oswald, on whom Otepka had failed to issue a State Department "lookout card."
While Robert may have suspected conspiracy in his brother's death, he never publicly challenged the FBI's findings. Meanwhile, Hoover removed his private phone link to the Attorney General and did not speak to him for six months, after which Robert left his post. Four years later, on the verge of capturing the Democratic nomination for the 1968 Presidential race, Robert was killed by another alleged lone nut, Sirhan Sirhan. He may have taken to his grave the secret of his brother's missing brain, which was removed (along with photos and 119 slides of tissue section) from the autopsy materials before 1967, probably on orders from Robert himself, according to the HSCA. Did he take this evidence into safe-keeping because he intended, once he became President, to reveal a conspiracy cover-up?
