Wiegman Composite:
Showing TSBD employees standing in a line, spread out from the corner of the building to the traffic light on the concrete island.

"................corner of the building to the traffic light on the concrete Island".
If the above description is true, then images of DPD Officer Baker, 20 seconds after the kill shot, would show him plowing through this tightly compacted string of people as he ran from the Island into the street. We do Not see Officer Baker doing anything like this on the Couch/Darnell Films. Bearing this in mind, and the opening frames of the Darnell Film showing the driver of Camera Car #2 standing flatfooted outside of his car, reveals that the 20 seconds after the Kill Shot timeline attached to the images of Office Baker crossing from the Island onto the street are Incorrect.
The Couch, Darnell, and Wiegman Films are dominoes. They rely on each other to corroborate their assigned timelines and the images captured on them. Those films assigned timelines are All Incorrect. And purposely so. Roughly, we are talking about a missing 25-30 seconds here. That's not a tremendous amount of time, until you consider that Wiegman did film the JFK Limo going under the Triple Underpass. Adding 25-30 seconds to the accepted Wiegman Film Timeline, then puts the JFK Limo on Elm St longer than has been accepted for 62+ yrs. And the extended timeline of the JFK Limo on Elm St then topples into another domino. The Zapruder Film.
