Wasn’t there a book pushing that theory? That has always sounded plausible to me based on Occam’s razor. If there really was something explosive being covered up, then wouldn’t you think that either a right-wing (Nixon, Reagan) or left-wing (Clinton, Obama) administration would want the truth exposed? Saving this guy’s family from disgrace sounds like the only argument for keeping quiet that everyone would agree to. Especially since its revelation would not advance any cause one way or the other.
I saw the film on Netflix a few years back...
Was John F. Kennedy Accidentally Shot And Killed By A Secret Service Agent?
