He just thought it up and did it, having read that Kennedy's visit to Dallas would pass right by his place of employment.
Ever since then, the radical left wing has been making up ridiculous conspiracy theories to distract the American people through manufactured doubt that one of their fellow travelers murdered the President of the United States.
I tend to agree Lee Harvey Oswald did it (and nobody need read all of the following, a general comment on the thread), he was into Russian stuff when he was a Marine like learning the language on his own and reading Russian publications, he got court-martialed, he'd been in trouble as a juvenile. He really did lie about a lot of things and unfortunately, he did beat his wife per the Warren Commission testimony and someone at one of the apartments where he lived once reported it to, landlord or police, I forget. Also, his alleged "Fair Play For Cuba" activities in New Orleans.
Then, if there were Conspirators, doesn't seem like any were ever seen with him. So, in the end, I think he had the make-up of someone who would do such a thing, along with the sad killing of Officer Tippit which has witnesses.
Must have been a crazy time, there are forums that talk about the JFK assassination to go into these issues more in depth and the conspiracies are too many and often too wild, the referred to link in one of the posts above seems to have a blurb that James Earl Raye did not kill MLK and I watched the special on James Files, I don't think he, who has confessed as well, did it either.
Just little that is convincing and I know, some people are hard-core JFK assassination conspiracy believers so I'm not really knocking that in general though some of the theories yes, are left-wing motivated.
I agree. He bought the rifle by mail order using a phony name so that no clerk in a gun store could ever say, “Yup, that’s the man I sold the rifle to’’.
