I've seen that and I don't buy it. Look at the Zapruder. Connelly is facing forward and is sitting fairly close to his door when Kennedy is hit through the back. Connelly is [b]still[/b] facing forward when JFK puts his hands to his throat. Then Connelly begins to turn around. All I can say is, the bullet that came out JFK's throat did not hit Connelly unless it bounced off of something or otherwise changed trajectory.

Finally, the fact that Connelly's wound was oblong proves the bullet hit SOMETHING else before striking him. What was that, do you suppose?
