Undercover History : CIA Secret Experiments

November 28, 1953: US Army scientist working on biological weapons, Dr. Frank Olson, falls to his death from his hotel window under suspicious circumstances. June 5, 1968: at a public event, Sirhan Sirhan fires eight rounds from a .22 caliber revolver into Robert Kennedy, striking him dead. Yet after arrest, Sirhan claims he has no memory of the crime; even hypnosis fails to stir the memory. 1975: the US government offers Olson's family a $750,000 payout, revealing that he died because of his involvement in "Operation Artichoke," a secret CIA experiment studying the use of LSD and interrogation, an offshoot of a series of mind control experiments called MK-ULTRA. What was the true extent of these secret CIA experiments, and their casualties? Could Sirhan Sirhan, as some claim, have been the product of MK-ULTRA and the Agency's efforts to build the perfect assassin?
