If one looks for who did have motive, Johnson stands out as the one individual who had the most to gain. His own lawyer says he was "guilty beyond a reasonable doubt" of having Kennedy murdered. His long time mistress, and mother of his son, is sure he had at least foreknowledge of it. A Texas grand jury would have brought formal indictment against him in another political assassination if he hadn't died already. Further, he had the opportunity to help set the time and route of the motorcade, control the initial investigation, preempt authorities from performing their normal functions, and appoint the Warren Commission as a body directly under him. Of course that commission was unable to discover that the unidentified fingerprint found in the "sniper's nest" belonged (34 points of match) to Johnson's buddy, convicted murderer Mac Wallace.
