Sam Kinney was the driver of the backup car behind the JFK limo and he saw the back of the head wound as it was being blown out from JFK's head. Not only were the motorcycle patrolmen hit with brain matter and blood , Sam Kinney said the limo he was driving had brain matter on it as well as his left arm . Those people were hit hard with blood and brain matter . Jackie got on the trunk to possibly scoop up brain matter or maybe a piece of skull . Jackie did not remember going out on the trunk lid. Clint Hill said that Jackie was trying to retrieve a piece of JFK's skull. If the motorcycle policemen and Kinney were to drive thru a mist of JFK's head wound , it would not look like they had been blasted with the brains and blood matter of JFK . The limo was going very slow, if not a complete stop. There is a picture of the JFK's limo that shows the brake lights on . The Zapruder film never shows a slowing down or a stop . Hargis says he couldn't figure out why Greer slowed down almost to a stop. Hargis says maybe his (Greers) orders was to "Slow Down" !!!!!!!
With all due respect, Sam Kinney couldn't have possibly had "brain matter" on his left arm. Kinney's arm is not resting on the car door and there is no way "brain matter" would have landed on his left arm alone without splatter/spatter landing all over him. Kinney could not have seen the back of the head erupt because the back of the head was not damaged. The proof of this lies within: A. The Zapruder film. B. The Mary Ann Moorman Krahmer photo, C. The Marie Muchmore film D. The statements and interviews by Bill and Gayle Newman, Abraham Zapruder, Marilyn Sitzman and Bobby Hargis. All of them mentioned the "side of the head" and three of them pointed to the location of the head wound, Zapruder, Mrs. NEwman and Mr. Newman. All captured on film.
No where do any of these people ever say anything about being "hit hard" by head matter. That was started by Josiah Thompson who took great liberty at making Hargis' description of the blood and brain" "hitting" him. It didn't "hit him" He drove into it as he indicated. And Martin didn't witness the head shot, nor did he even know head matter landed on him until much later while he was directing traffic . It's in his Warren Commission testimony.
No, Clint hill did not say that Mrs. Kennedy was trying to retrieve a piece of skull. Read his Warren Commission testimony, please.
Mrs. Kennedy did not exit the rear seat to possibly "retrieve" skull or brain. There is absolutely no proof of this, only rumor, and her actions in the Zapruder film rule this not to be the case. If you read what Hill said, he said he
thought he "saw something come off the back of the car" but he couldn't be certain. He then mentioned that a piece of skull was turned over to them the next day, but his description of whom turned it in sounds like the Harper fragment because Hill thought it was turned in by a "medical student", which would be Billy Harper. The Harper fragment was found several yards ahead of where the limousine was located at the time of the fatal shot.
There is no proof of brake lights captured in the on position in any of the films or photos. That is just speculation. One frame of the Marie Muchmore film captured the right rear brake light at the moment of the fatal shot, but there is not enough there to prove that the brake light was on. Aside from, this, we already know that the car was slowing to 8 MPH from the 11/12 MPH it was traveling down Elm Street until just before the last shot when Greer turned to look to the rear. All films show the limousine slowing--including Zpruder.
