I never realized Kennedy was so dangerous to the establishment. Is that why?
Well that's the real question, isn't it? Why? The how and the who is just scenery for the public. Oswald, Ruby, Cuba, the Mafia. Keeps 'em guessing like some kind of parlor game, prevents 'em from asking the most important question, why? Why was Kennedy killed? Who benefited? Who has the power to cover it up? Who?
