What do you mean by "enhancement"? What EXACTLY did you do to that image? Did you add that antenna to the image?
The first clip from the Mark Bell Film shows Zapruder walking from his perch and at the last second turning back toward the pergola... And we see Sitzman turned toward the pergola, and Charles Hester standing in the background, and his wife, Beatrice, still sitting on the ground where he left her... The next clip from the Mark Bell Film shows Zapruder in the pergola with his back to the camera, Sitzman still turned looking around, and Charles Hester standing in the background...The last clip shows Charles and Beatrice Hester in the pergola, with Zapruder who is most likely talking on a walkie-talkie...Yeah... Very likely they were all part of the dirty deed...
Just look at the Bell film/2nd snippet down from the top. There is a dark figure already inside the Shelter. This is supposed to be Zapruder already inside the Shelter. As you see, Mr Hester is standing well (E) of this same shelter and Mrs Hester is nowhere in sight. That Darnell snippet shows Mr and Mrs Hester ENTERING the Shelter AHEAD of Zapruder. Are you claiming that Zapruder went in-and-out of that shelter 2 times? You have timeline issues with the Bell Film images of Zapruder and the Darnell Film images of Zapruder. Or, are we seeing 2 different men dressed in very similar suits and hats?
Before cellphones...Who are these guys talking to?Zapruder on a walkie talkie... later crying crocodile tears.Yeah, most likely part of the plot... [Z. = top right]
Perhaps we should add this fellow to the group...
