I'll ignore your attempt to lower the conversation to insult trading. But since you seem to be claiming (say so if you have merely overstated your case) that "every fact in the case" supports the view that Oswald acted as a lone assassin, and that no conspiracy to commit or cover-up the murders existed, please explain how the testimony of Earline Roberts to the fact of a police car stopping and honking while Oswald was briefly at the rooming house supports Oswald's acting alone.
Further, it is not I, but you, who has drug in the rank speculation about Oswald's possible motive. (The postulates of Posner) I have directly stated that LBJ did have a definite and obvious motive, becoming president. Do you deny the truth of that direct statement?
