If I didn't "follow your argument," it's because you haven't actually made one. So far, you've managed a tautology, an unsupported assertion dressed up as a question, and a non sequitur. Your "examples" don't address or rebut the point I made about the amount of manpower pressed into service in the investigation.
However, your continuing fascination with finding "secret Nazi's" betrays the idols that you pray to. And that your information is carved from the loose, weathered boards you've been prying off of shipwrecks dotting the shores of the Crackpot archipelago.
After these fascists killed JFK they put into power LBJ (who was one of them too). LBJ then proceeded to use the assassination, to cite it, to pass civil rights. Yes, the fascists who wanted to stop the traitor Kennedy because of his liberal policies then saw LBJ *use* their act to end racial fascism. Oops. LBJ then ended the covert war on Cuba, the fascist program to kill Castro; which was pushed by the Kennedys anyway and with JFK dead RFK was no longer interested in pushing it. In any case, it ended with JFK's death; the one the fascists did. Double oops. But one more: then the fascists who killed JFK staged a fake investigation that *cleared* Castro. Yes, the fascists who wanted war to overthrow Castro cleared him of any involvement and thus a cause for his removal. Triple oops.
But one more again (okay, it's really two more) then after being elected, LBJ proceeded to pass the most liberal/progressive policies in US history. Yes, the fascist LBJ and the fascists who put him into power then enacted the most anti-fascist set of policies in American history. Oops again.
In conspiracy world this all makes sense. In this one, not so much.
