The real conspiracy Oliver Stone doesn't want you to know

I’m partial to the theory that Kennedy’s head spontaneously exploded, a rare but not unheard-of phenomenon, and the authorities hurried to find and frame some schmuck for shooting him, because the idea that an assassin could kill the President would lead to far less existential terror and mass panic than the idea that the President’s head could spontaneously explode without explanation, as could anybody else’s.
