This morning, I called a friend of mine who is a Professor of Physics at a Florida college, and I asked him a question about the Dave Wiegman film. The question was: since Dave Wiegman was swinging around to the right (clockwise) to pan the doorway, and he had to reverse that motion to swing back around to the left (counterclockwise) didn't he have to come to a complete stop in-between in order to do that?

This was his reply to me:

"Velocity is speed plus a vector. The vector determines the direction, but the speed is represented by the length of the vector. To reverse direction, the vector has to flip, but it can't flip unless you bring it to zero. The length of the vector must shrink to zero before it can begin to grow in the opposite direction. So yes, to reverse the direction of a moving object, it must first come to a complete stop. And the same is true in the case of angular velocity, which you are describing."     

What caused me to think about this is that in the Wiegman film, Dave seems to be moving too fast during his second pan of the doorway. And when he gets to the end of his rotation, his swinging around to his right, he does not appear to stop. 

It happens in the 4 second mark of this film, so watch the first 5 seconds.

What I'm saying is that the transition from swinging right to swinging back left happens too fast. It was faster than Wiegman could do. They must have removed frames to speed it up, just as they did with the Zapruder film. In the Z-film, they removed frames to hide the slowing and stopping of the limo, which we don't see in the Zapruder film. 

If the limo didn't come to a complete halt, it must have slowed down to less than 5 miles per hour. How else, could Clint Hill jump off one car and catch up to another car in front of him? A brisk walking speed is 4 miles per hour. How much faster than that could Clint Hill have been going? And even if you think he was capable of going faster, it takes time to accelerate. It takes time to get up to speed. So, the very fact that he was able to do that tells you that the limo in front of him had stopped or nearly stopped, which we don't see in the Zapruder film because they removed frames from it. 

In the Wiegman film, Wiegman must have heard something or saw something through the corner of his eye, for why else would he swing around to capture the TSBD doorway again? The action was down Elm Street. The President was down Elm Street. So, Wiegman must have heard or saw something which provoked him to swing back to the doorway again. What was it? I don't know, but I do know what the result was. The result was that Doorman was gone. He left. So, the film alterers implanted a new Doorman so that one would be there. Look at this frame from the Wiegman film:



As Wiegman frames go (and it's a very blurry film) this one is very sharp, and we don't see it this sharp in the film.  I don't know where it came from. But, doesn't the sharpness of it tell you that Wiegman's camera had to be still at the time? I'm saying that the guy in the upper right hand corner, right along the edge, wasn't really there. I'm saying that they put him there as a still image. Now, how long could they let people dwell on him since he was just a still image? Obviously, not very long, or the jig would have been up.  And that's why they sped up Wiegman's second pan of the doorway, so that no one would notice that he was a different man than the first Wiegman Doorman (who was Oswald) and that he was inserted there to replace Oswald (who had left), and that he was not moving or responding or doing anything at all.  

What they did was edit the Wiegman film by removing frames so that we get the most fleeting glimpse of the second Doorman- just long enough to register that he was there, but not long enough to realize that he was a different man than before and not really part of the scene.
