Greer changed story in the days after he killed Kennedy

Agent Greer to the FBI 11/22/63: "Greer stated that he first heard what he thought was possibly a motorcycle backfire and glanced around and noticed that the President had evidently been hit [notice that, early on, Greer admits seeing JFK, which the Zapruder proves he did two times before the fatsal head shot occurred]. He thereafter got on the radio and communicated with the other vehicles, stating that they desired to get the President to the hospital immediately [in reality, Greer did not talk on the radio, and Greer went on to deny ever saying this during his WC testimony]…Greer stated that they (the Secret Service) have always been instructed to keep the motorcade moving at a considerable speed inasmuch as a moving car offers a much more difficult target than a vehicle traveling at a very slow speed. He pointed out that on numerous occasions he has attempted to keep the car moving at a rather fast rate, but in view of the President's popularity and desire to maintain close liaison with the people, he has, on occasion, been instructed by the President to "slow down". Greer stated that he has been asking himself if there was any thing he could have done to have avoided this incident, but stated that things happened so fast that he could not account for full developments in this matter(!) [the "JFK-as-scapegoat" theme…and so much for Greer's remorse from earlier the same day!]."(Sibert & O'Neil Report, 11/22/63)

Agent Greer to the FBI 11/27/63: "…he heard a noise which sounded like a motorcycle backfire. On hearing this noise he glanced to his right toward Kellerman and out of the corner of his eye noticed that the Governor appeared to be falling toward his wife [notice that Greer now mentions nothing about seing JFK hit---he does the same thing in his undated report in the WC volumes (18 H 723)] He thereafter recalls hearing some type of outcry after which Kellerman said, "Let's get out of here." He further related that at the time of hearing the sound he was starting down an incline which passes beneath a railroad crossing and after passing under this viaduct, he closed in on the lead car and yelled to the occupants and a nearby police motorcyclist, "Hospital, Hospital! [nothing about using the radio this time out]" Thereafter follows a complete physical description of Greer, as if the FBI agents considered him a suspect, inc. age, height, and color of eyes! (Sibert & O'Neil Report, 11/29/63)

Greer realized several days later how incriminating his actions were and lied. HE WAS A STUPID GOON.
