Who is sitting up in Zapruder @Z456?

[Steve M. Galbraith]

I wonder how he's going to pull that one off. The small head movement forward is in full view, and would have snapped back about the same distance if not aided by other physiological factors.

From the Amazon site for his book: "The sudden two-inch forward movement of the president’s head in the Zapruder film just before his head explodes is revealed to be an optical illusion caused by the movement of Zapruder’s camera. This leaves without further challenge clear evidence that this shot came from a specific location to the right front of the limousine."

I don't know how one can claim that it "leaves without further challenge clear evidence that this shot came from a specific location to the right front of the limousine." Thompson argues a second shot then immediately followed this one; one from the right front, another from behind.

If Zapruder's camera motion/movement caused the "apparent but not actual" movement of JFK's head then why didn't Jackie and JC also show this "optical illusion"? Shouldn't everything in the frame move, or appear to move, as well?

Thompson's a smart man so these questions are probably addressed.

Smoke and mirrors: Nothing else moves in concert with the head so it better be one hell of an explanation.

It's clear from this clip that the first movement of JFK's head is forward at the moment of impact:
