Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

I quoted Officer Hargis, who was the closest person to the limo, saying that it stopped. Here is Senator Ralph Yarborough:

"Senator Ralph Yarborough sat the on the back seat behind the driver of the Vice-Presidential car. From his 10-64 affidavit: “As the motorcade went down the slope of Elm Street toward the railroad underpass, a rifle shot was heard by me; a loud blast, close by….When the noise of the shot was heard, the motorcade slowed to what seemed to me a complete stop (though it could have been a near stop). After what I took to be about three seconds, another shot boomed out, and after what I took to be one-half the time between the first and second shots (calculated now, this would have put the third shot about one and one-half seconds after the second shot…) a third shot was fired. After the third shot was fired, but only after the third shot was fired, the cavalcade sped up…" (Interview with Jim Marrs as published in Crossfire, 1989)

Now, whether the limo actually came to a complete, dead stop or nearly so doesn't matter. It amounts to the same thing. And having removed frames from the Zapruder film to hide it, of course they would alter the other films similarly. 

This is the trailer to the The Zapruder Film Mystery which features Doug Horne and Dino Brugioni, in which Dino states that the film was altered. He even states that the images were "sharp" as opposed to how they are now. Recall how I said that the Wiegman film was deliberately blurred.
