 A further irony is that Chief Justice Earl Warren, enlisted by Lyndon Johnson to rubber stamp the preordained conclusion that Oswald murdered President Kennedy, wrote what seems to me a brilliant dissent when the U.S. Supreme Court affirmed the Hoffa conviction. I asked a friend of mine, I'm not saying this, I asked Richard A. Posner, well, do you agree with me about Earl Warren's dissent there? And I have to tell you, he did not. He did not. Bobby Kennedy then sent Sheridan to New Orleans, as Sheridan freely admitted, to destroy Jim Garrison.
