Dan Rather's laughable account of what he thinks he saw in the Zapruder film

Alvarez' deceleration calculations are centered around two different linear regressions. Each is derived from data over dozens of frames, so it is not a particularly accurate representation of what happens right around the deceleration. The ANTDavisonNZ panoramic version of the Zapruder film gives you a much better picture of what happened, and the slowdown shown there is pretty abrupt.

This version of the Z-Film, created by New Zealander Ant Davison, is the reason I got into the JFK debate. It is a remarkable achievement.
He uses the z-frames to create a backdrop against which we can see the limo move. The limo's deceleration, to almost walking pace just before the head shot, is clear for all to see. The reason it is difficult to detect in the actual Z-film is because the background is mainly green grass so there is no point of reference to visually grasp the deceleration. It is also a relatively tight camera shot, which also makes it difficult to detect with the naked eye.
Davison's version of the Z-film ends this debate. Michael's claim, that the Z-film doesn't show this deceleration, is blown out of the water.
Doubtless he will do what he always does when confronted with irrefutable evidence that blows his arguments away - go quiet for a while before returning with the same baseless claims.

Davison's version of the Nix film:

An obvious effect of the deceleration is that the flanking motorcycles suddenly catch up with the limo as it rapidly decelerates.
