Who killed Kennedy? Many keen minds have their doubts about the findings of the Warren Commission. Could Oswald have fired 3 shots in 5.6 seconds with the inaccurate rifle he had - and hit a moving target? Did he even kill patrolman Tippit (the bullets in the body were smaller than the barrel of his revolver)? Was the brown paper bag made only to attract attention? Was Bullet No. 399 a plant? Suppose there was a Second Oswald - a man very similar physically and an expert marksman?
