It has been the position of the commission that one man, Lee Harvey Oswald, was stationed at the eastern most window on the 6th floor of the Texas School Book Depository Building, which is located on Elm Street. It has also been the official government opinion that Oswald acted alone in murdering John F. Kennedy and that there was no conspiracy of any kind behind the crime. A rifle was found on the 6th floor of the building. This 6.5-mm bolt-action, c1ip fed, 1938 Mannlicher-Carcano belonged to Oswald. Keeping in mind the Warren Commission's hypothesis that the 2nd shot went astray near Tague, and that the last bullet was the fatal shot striking the head, only one bullet is left as the cause of all other gunshot damage. Only 3 shots at most could have been fired using this rifle in the 5.6 seconds that elapsed from the last possible moment that Kennedy could have received the 1st wound (when he emerges, hit, from behind the sign in the Zapruder film), to the easily recognizable moment of the last fatal shot to the head (Kennedy reacts violently in the film at the moment of impact).
Sitting directly in front of the President in the Lincoln limousine was Gov. John B. Connally of Texas. He was sitting in one jump seat and his wife, Nellie, was in the jump seat next to him, directly in front of Mrs. Kennedy. Governor Connally was hit in the back, the bullet exiting from the right side of his chest, transiting his right wrist, and lodging in his left thigh. If the Commission is right about the number of bullets, the same bullet that struck Connally must have struck Kennedy 1st. That is to say, the bullet that hit Kennedy in the back would have had to exit from his body and gone on to strike Connally.
If Oswald was firing from the 6th floor of the building, the angle of trajectory would be 17 degrees, 43 minutes, 30 seconds, in a downward direction. That bullet entered Kennedy's back, 5½" from his collar line--yet the only wound on the President's body, in addition the wound in his head and the entry wound his back, was a small slit in his throat. The Warren Commission theorized that this slit was caused by the exit of the bullet that entered Kennedy's back and continued on to hit Governor Conally. But since this bullet struck no bone in the President's body which might have deflected it's angle of trajectory but exited in an upward direction, it seems very apparent that the single bullet theory of the Warren Commission is a geometric impossibility.
