Storing,
You seem to be saying that Zapruder, wanting to capture every possible millisecond of JFK and Jackie on film, even filmed the limo's turning onto Elm Street (which was easy for him to anticipate because he could see the limo approaching on Houston Street), and the reason we don't see that part of the film today is because the bad guys, needing to hide the first, missing-everything SHOT FROM THE FRONT that happened at that time, edited-out about five seconds of that part of the film, and this explains why the limo implausibly POPS onto the film, already a considerable distance down Elm Street at Z-133.
Have you considered the possibility that the reason Zapruder didn't capture the limo's turn onto Elm Street was because:
1) Detecting a pause in "the action," he decided to rewind his new camera and/or
2) He intentionally waited until the limo had straightened out on Elm Street to resume filming?
Regarding Dan Rather's assertion that he had viewed the Zapruder film one whole time and watched in it the limo as it "turned onto Elm Street," I would attribute that to poetic or journalistic license.
I mean I mean I mean (to use a phrase often uttered by Jim DiEugenio), how else could he put it to the rapt national audience?
"The Presidential limousine, carrying handsome and well-tanned President Kennedy and his resplendent wife, Jackie, doesn't actually appear in the Zapruder film until it's already traveled about one hundred feet down Elm Street . . . "
(Yawn)
Let's take a closer look at your silly scenario, Storing.
If there was a very early shot from the front that implausibly missed everything, what evidence of it was caught on the Zapruder film (the part that the bad guys edited out)?
The bullet's impacting a spectator or hitting a building and causing sparks to fly?
Several spectators simultaneously gasping and throwing themselves to the ground?
What?
