Not to mention the fact that Coretta Scott King proved this in court some years ago:

This verdict is not only a great victory for my family, but also a great victory for America. It is a great victory for truth itself. It is important to know that this was a SWIFT verdict, delivered after about an hour of jury deliberation. The jury was clearly convinced by the extensive evidence that was presented during the trial that, in addition to Mr. Jowers, the conspiracy of the Mafia, local, state and federal government agencies, were deeply involved in the assassination of my husband. The jury also affirmed overwhelming evidence that identified someone else, not James Earl Ray, as the shooter, and that Mr. Ray was set up to take the blame
