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

[Royell Storing]

 "......what is obvious to the naked eye"?  Have you ever watched a "Fast & Furious" flick? NOTHING on film is, "obvious to the naked eye".

[Mitch Todd]

You can't be serious. First off, there is no "noticeable" stop or slowdown in the Zapruder film. Even when you watch the film at half speed, there is no discernible slowdown, much less a stop. Second, several witnesses said the stop/marked slowdown occurred before the head explosion, but Hill did not start to move toward the limousine until after the head explosion. Officer Hargis, for example, said he was hit with blood and brain spray after the limo stopped.

Dr. Luis Alvarez detected a 4-mph slowdown in Z295-304, i.e., in 10 frames/546 milliseconds. Obviously, this event is undiscernible when you view the Zapruder film at normal speed, which is the speed at which witnesses viewed the shooting. In fact, the slowdown happens so quickly that no one noticed it until Alvarez detected it through careful frame-by-frame analysis of the film. This cannot be the stop or marked slowdown described by 40-plus witnesses.

Furthermore, speaking of the Muchmore film, in that film the limousine's brake lights come on for nine frames during the time period corresponding to Z311-319, but this event is not seen in those Zapruder frames, not to mention the fact that several witnesses said the stop/marked slowdown occurred before JFK's head exploded.

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.

  How can anything be based on a film that flunks the "chain of custody" and was privately locked up for 15 yrs? That is silly.

Storing,

How many bad guys do you figure were involved, altogether, in the planning, the "patsy-ing," the shooting, the getting-away, and the all-important (and obviously ongoing!!!) cover up?

Just a few, or oodles and gobs?

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.

The ability/willingness of WC apologists to ignore self-evident reality is amazing.

So now you are saying that Alvarez, an ardent WC defender, somehow missed the slowdown that you claim is visible in the current Zapruder film! He studied the film frame by frame for years before he detected the Z295-304 slowdown, but according to you he somehow "missed" the slowdown that you claim to see. You folks can't even agree on when your alternate slowdown occurs.

Look, nobody but you and some other WC apologists sees any noticeable slowdown in the Zapruder film when viewed at normal speed, which is the speed at which the witnesses would have seen the motorcade. Forty-plus witnesses would not have described your alleged slowdown as a stop or near-stop. Watch the Zapruder film at 0.75 speed and you still won't see a hint, a trace, of a slowdown, much less a stop. We all know it. But you guys can't admit it because you don't want to admit that the Zapruder film has been altered.

And I notice you've said nothing about the conflict between the Muchmore film and the Zapruder film on this point. In the Muchmore film, the limousine's brake lights come on for nine frames during the time period corresponding to Z311-319. However, no such event is seen in those Zapruder frames, not to mention the fact that several witnesses said the stop/marked slowdown occurred before JFK's head exploded.

Some witnesses specified that the stop/slowdown occurred right after the first shot, while others made it clear that the event occurred before Jackie began to crawl out of the back seat and onto the trunk.

If you put your foot on your brake pedal for half a second, your car is going to very visibly slow down. Officer James Cheney said that several officers told him the limo "stopped completely."

There may have been two stops/marked slowdowns. A number of witnesses said the car came to screeching/dramatic/sudden stop right after the head explosion. Some of them said the limo pulled over to the curb after the head explosion. We don't see any of this in the current Zapruder film either.
