Single Bullet Theory Law and Legal Definition

Single bullet theory is a crucial element of the Warren Commission's conclusion that Lee Harvey Oswald acted alone in the assassination of President Kennedy.

According to the Warren Commission, three shots were fired. The first shot did not cause any significant damage or injury. According to these tests all of the Governor's wounds could be explained by a single bullet. Under the assumption of appropriate relative positions of President Kennedy and Governor Connally in the car, the ballistics experts considered it also plausible that the same bullet that passed through the President's neck could have subsequently inflicted the Governor's wounds. The Commission concluded that it was probable that the President's neck wound and all of the Governor's wounds were caused by a single bullet.
