There's no logical way some two bit hoodlum and thief would break out of prison, get an expensive,(about $300.00 at the time) high powered hunting rifle, and go out to assassinate the nation's foremost civil rights leader without a lot of serious support from important people. Then Ray went on the run around the world, assuming a host of identities that somebody else had to research for him and supply to him. Finally, he was represented by Percy Foreman, Texas' most prominent criminal defense lawyer, who promptly sold him out by pleading him guilty and getting him a life sentence.
As far as motive's concerned, LBJ's the one. By the timer of the assassination, MLK had become a royal pain in the fundament and embarrassment for LBJ. Remember, LBJ had turned most of the nation's civil rights policy over to MLK. MLK showed his appreciation by engaging in all sorts of sleazy sexual affairs, apparently some with seriously underage females; running "civil rights demonstrations" that promptly became riots, conveniently just after he left; attacking LBJ's Vietnam policy; and generally demanding something close to a socialist revolution. All of these shenanigans seriously undermined the DemonRats' and LBJ's efforts to retain their illicit power. Hence, the logical solution for LBJ was the "Final Solution to the MKK Problem," which he brilliantly applied, while he and the MSM blamed conservatives for the assassination, thereby enabling LBJ to continue and intensify his own socialist policies.
Good analysis, but you left out ol’ J. Edgar Hoover’s part.
You might also recall that a lone teenager with no source of income stalked George Wallace until an opportunity to shoot him arose. George announced his run for President in Texas.
