I don't believe that all bullets fired in Dealey Plaza came from one person.
According to the Warren Report:
1. One missed the car (concrete chips hit a man in the face)
2. One hits Kennedy in the back/neck (depending on what you believe), tumbles, hits Connally sidewise in the back, and his wrist. Bullet ends up with virtually no damage to it.
3. One hits Kennedy in the head and kills him.
HOWEVER, other information:
1. Acoustical evidence of shots fired in Dealey Plaza and analysis of corresponding noises on a tape, from a microphone on a motorcycle in the motorcade, indicated that there were more than 3 shots. (Done by the House Committee on Assassinations in 1977).
2. The physician at Parkland Hospital stated that the neck wound was an entry wound, not an exit wound. (This was used for a tracheotomy, however, so no one could tell what it was later-exit or entry). This was an experienced trauma emergency room physician.
3. Witnesses heard shots come from the knoll next to the Dealey Plaza pergola, and went up there after the shots were fired to see if anyone was back there. (This is corroborated by photographs).
4. Witnesses saw a man open a black umbrella next to the street, and move it up and down several times as the motorcade passed--this was on a hot SUNNY day in November. It is believed that this may have been a signal to everyone to start firing.(This is also corroborated by photographs. He was located in front of a street sign next to Elm Street, slightly in front of Zapruder.) (A man came forward in 1977 to claim that he was that person, and brought forth the umbrella that he used. However, it was not a match to the umbrella in the photograph. He was not considered credible).
5. Governor John Connally, and Jean Hill, the teacher famous for photographing the event, both stated that one shot first hit JFK, then one hit Connally, then the fatal shot. That means there were four fired if one missed the car !
6. The Secret Service agents said the last two shots were like "bang-bang," thus, too close together to be fired by the same rifle.
7. John Connally shouted "No, no , they're going to kill us all."
Jackie Kennedy, at the airport, stated that she wasn't going to change clothes when the oath of office was given to Lyndon Johnson. She said that "I want them to see what they've done." Both of these individuals obviously believed that more than one person was involved at the time of the shooting.
8. The Dallas PD issued an "all-points" for a single shooter, Lee Harvey Oswald, within 45 minutes of the shooting, yet there is no clear evidence as to how they found out that this was the ONLY person that they were to be looking for. Oswald was just one person who happened to have been spotted in the first floor cafeteria as the motorcade passed by, by a witness.
9. A flash of recognition crosses Oswald's face right before he is shot by Jack Ruby. These two men knew each other. Very odd coincidence.
Too many loose ends.
