Kennedy assassinationBill Cooper Radio Broadcast 1997
In Behold a Pale Horse, Cooper asserted that John F. Kennedy was assassinated because he was about to reveal that extraterrestrials were in the process of taking over the Earth. According to a "top secret" video of the assassination that Cooper claimed to have discovered, the driver of Kennedy's limousine, William Greer, used a gas pressure device developed by aliens from the Trilateral Commission to shoot the president from the driver's seat. The Zapruder film shows Greer twice turning to look into the back seat of the car; Cooper theorized that Greer first turned to assess Kennedy's status after the external attack, and then to fire the fatal shot. Conspiracy theories implicating Greer reportedly "snowballed" after publication of Behold a Pale Horse. Cooper's video purporting to prove his theory was analyzed by several television stations, according to one source, and was found to be "... a poor-quality fake using chunks of the ... Zapruder film."
