JFK killing: How close was Jackie to being shot?

Jackie Kennedy or Nellie should have been injured by bullet shrapnel if the shot was from behind. Jackie's head was really close to Jack's at frame Z-313. I can see how people would believe the official story but it's still arugable that the film has been altered to cover up if Jackie was the shooter or the driver turned out to be the shooter.

If you have ever seen the Manchurian Candidate you will know exactly what I'm talking about or Executive Action, for that matter.

It would also explain why those two specific movies went out of public circulation for so long... they were too close to the truth.
