Oh, NO DOUBT, THIS HAS TO BE THE TWOOOOF!<quoted text>
Go to the library...pick up a book called 'Behold a Pale Horse' by William Copper and read it. THEN you will not only see how people can say such things but you will also no longer believe the possibility is bullshit.
According to Cooper, John F. Kennedy was assassinated because he was about to reveal that aliens had invaded and were in the process of taking over the Earth.
He claimed that a video of the assassination showed that the driver of Kennedy's limousine, William Greer, used a gas pressure device developed by the aliens from the Trilateral Commission to shoot the President in the head.
The Zapruder film shows Greer twice turning to look into the rear of the car. Cooper stated that Greer's first glance was to assess Kennedy's status after an initial attack and the second was to commence "Plan B" by shooting Kennedy himself.
Conspiracy theories implicating Greer were reported to have "snowballed" after the publication of Behold a Pale Horse.
