If only any of the conspiracy theories were honestly subjected to the over-the-top degree of proof that the Oswald lone-assassin finding. Through another conspiracy theory, they blame the mass media for not mindlessly spreading their theories, rather than the critics acknowledging their theories are to blame.
Is this an American thing? Do other countries have anything similar to the obsession over the JFK assassination? For example, in the UK, Jack the Ripper, while quite intriguing, never got this out of hand.
BTW, the British recently endured a conspiracy, in the form of the Post Office Scandal.
It's a baby boomer fixation (each anniversary the attention diminishes); the Kennedys were viewed as American royalty (Camelot and all of that); and people want to believe that the horrors of the Sixties, Vietnam and the deaths of RFK and King and other upheavals, would have been avoided if JFK survived. Add all of the other ingredients - spies and Cold War intrigue, a blurry film as sort of Holy Grail, interesting characters, JFK as King Arthur - and you get this almost mythological level of interest.
I would imagine the closest parallel today (but not real close) would be the death of Lady Di. It's remarkable how obsessed the British were over that.
Conspiracy theorists once asked good, fair, legitimate questions - even though their answers were wrong (to his credit, Epstein didn't try). Certainly at that time and maybe up through the 1980s. But now some 60 years later these are no longer good faith questions. This is Jim Garrison type paranoid nonsense. How many times do the backyard photos have to be authenticated? And they still don't believe it? The idea that people, real human beings, in the fractured, divided, split American government - federal and state and local bureaucracies with all of the divisions and conflicts - could plan this all out, execute it, and cover it up (even today!!) is preposterous. Worse than preposterous there's not credible evidence for it (where and when was this planned?)
