The JFK conspiracy theroy is just not allowed.

85. Any conspiracy theory that keeps inventing additional conspiracy theories to justify the original.

Do conspiracies exist? Absolutely. And the chances of success and undiscovery are fairly good when the conspirators number a handful or less. Look at the 2 Colombine conspirators, for example.
However, as the number of conspirators grows, the probability of success and undiscovery plummets pretty rapidly. All it takes is for one person to fuck up, encounter an unforeseen snag, or get liquored up and blab. Watergate. Iran-Contra.
Since the conspiracy du joir is the JFK assassination, let us examine it. There's the prime group of shadowy figures that organizes the assassination. They have to bring in hit-men. Local LE and FBI have to be organized the plant the evidence. WH staff and SS have to be brought in to make sure the parade route drives past Dealey Plaza. 2 dozen or more doctors and ER staff have to be told what to do. Then the autopsy staff of 30 or so has to be told what they are to find. Then theres all the film experts, ballistics experts, fingerprint experts, etc who have to recieve their instructions. Then theres the "clean-up" squad, to silence any loose ends. Jesus....were talking hundreds of people here, each in charge of a critical part of the operation and possessing some crutial knowledge of part of the conspiracy. Yet...no one fucks up. No one blabs. No-body has a vindictive ex-wife. No-body offers up knowledge of the conspiracy in a plea-deal for an unrelated crime. The odds of that happening are astronomical. Too many people involved. If there was a conspiracy to kill President Kennedy (and no doubt, many wanted him dead), it would be planned in a manner that involved AS FEW people as possible, with AS FEW witnesses as possible. 11/22 simply doesn't fit that model.
