Was the CIA "responsible" for Kennedy's death, because they coverd it up?

You make an interesting point. But, there's a difference I think, between getting someone killed by gross incompetence, and, actually intending to get someone killed, or killing them yourselves. I think the CIA made such an incredible mess of things here, that they had no choice but to cover it up, or face the end of their agency. Permanently. Let's give Fidel Castro some credit here! What a survivor! He arranged to kill the President of the United States in self defence, and he got away with it. Wow!! Sure, the CIA covered it up. They got the Mexican government to threaten the Nicaraguan undercover agent who witnessed the 6,500 dollar payment to Oswald, before he talked to the representative from the Warren commission. They said he'd be hung by his testicles if he told the truth. So, he told the Warren Commission representative he lied because he hated Castro, and was trying to get him in trouble. Like, Castro isn't allowed to defend himself! Then, after he'd been "discredited", he returned to his original story, which was the truth -- Oswald was indeed hired to kill Kennedy. But, what choice did the CIA have? Could they acknowledge that the President of the U.S. was killed by Fidel Castro in self-defense against them??! Could they acknowledge that they didn't twig there might be a slight problem in letting Marxist Oswald get interviewed by KGB assassins in Mexico after Fidel Castro publicly threatened the U.S. President's life? And then letting him get near Kennedy in Dallas? Could the CIA acknowledge after Kennedy's assassination by Cuban agent Oswald, that Cuban intelligence was much better at killing American leaders than the CIA was at killing Cuban leaders? I don't think so! That fact is, I think Kennedy might have died laughing at the CIA's incompetence, if Oswald hadn't killed him! And, after the rings Fidel Castro was running around them, you can't really blame the CIA for not wanting to mess with that guy anymore, can you? Too tough for us! So, I think the CIA probably was responsible for the death of JFK, but, I don't think they actually murdered him, or even really wanted him dead. Hell, I doubt they would have had the brains to figure out how to kill Kennedy, even if they'd wanted to!
