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.
The only logical conclusion, therefore, is that somebody hired Ray as a hit man, equipped him, provided him false identification, and financed his international flight. Then the same somebody provided him with an attorney, the Texan Percy Foreman, who deliberately punted the case and got Ray locked up and silenced for the rest of his life. All of that points inexorably to LBJ, especially because the MSM never found any Klan or other conspiracy.
