For forty years, the plea bargain of James Earl Ray for the assassination of Martin Luther King Jr. has been the subject of intense inquiry and debate among historians and researchers. Was Ray a small-town petty thief really the criminal mastermind the Shelby County, Tennessee, prosecutors said he was? Or was he a pawn in a broader conspiracy that involved an entity much more powerful: the U.S. government? In reality, evidence reveals James Earl Ray was inducted into the CIA as a young man in the U.S. Army and subjected to mind control experimentation in the same era when psychological drugs are known to have been administered by the armed services to unknowing recruits in an attempt to control human behavior. Later, in the two years prior to the King assassination, Ray was under the influence of several government-connected hypnotists seemingly working to make him an obedient patsy. Ray's case never went to trial, and many, including the King family, concluded that there had been a conspiracy, yet a government investigation in 2000 revealed that there was no evidence to suggest it. In Truth At Last, Ray's eldest brother John Larry Ray and Martin Luther King Jr. historian Lyndon Barsten, offer incontrovertible evidence that James Earl Ray could not have assassinated Dr. King.
