Here is the problem with the 911 conspiracy theory's......

142. Neither

> Is Jackie moving forward too? Or is Mrs. Connally's shoulder jerking back rapidly?

Neither! Mrs. Connally's arm is just motion-blurred to the left, like everything else. Her elbow appears to move to the left the same amount as the back of Mr. Connally's head, the left edge of the door handle, and Jackie's elbow, while the white lines shows that the right edges of the images are all aligned with 312, so that's all motion blur toward the left, as I said.

The image is absolutely conclusive: The Zapruder film shows that JFK's head suddenly snapped to the right between 312 and 313, the exact same time frame that he was hit. When you watch it at full speed, you can actually see the snap; that's what made me look at individual frames in the first place. And significantly, this evidence is perfectly consistent with all the other evidence that says JFK was shot from behind and the complete lack of any credible evidence of a shot from anywhere else.
