All you have to do is look at the clearer Darnell Film frames after that 1st frame.

Like this frame.
Like this frame that clearly shows, beyond any shadow of a doubt, that the Thornton sign is covering where Zapruder and Sitzman are?
Does it matter that I've shown you this frame?
Does it make any difference?
Use your eyes and a tiny portion of your brain.
Use intelligence.
Once again, for the third time, we have your claim that Weigman can be seen moving across the knoll. This is a lie. This is a deliberate falsehood. Why are you lying about this? Time and time again I have to show that you are lying about this but you carry on saying it.
Unfortunately, it appears you are a pathological liar and fantasist.
It really is a shame..
You've done extremely good work concerning the Prayer Man and the activity around the TSBD immediately after the Kill Shot. And your theory of Shelley and Lovelady entering the TSBD via the front door is unique. All of this is to your credit. I made the mistake of thinking that your knowledge of the JFK Assassination was also this broad based. At this point, it's not even close to that level. You need to familiarize yourself with the 11/22/63 layout of the Knoll. Also, who was where, who went where, and what JFK Assassination Films and Photos document this. Start with the Couch Film. The Couch Film shows what is believed to be Wiegman running Down the (W) side of the Knoll. The Bell Film shows Wiegman on the upper (E) side of the Knoll. How much time do you think is between the Bell Film images of Wiegman on the (E) side of the Knoll vs the Couch Film showing Wiegman running down the (W) side of the Knoll? And remember that we see Officer Hargis standing alongside the Light Pole on the Bell Film. TICK/TOCK
Get to know the JFK Assassination Images, (both film and photo), and think it through. If you do this, you will Not have to rely on smokescreens like, "Zapruder, Sitzman, and Wiegman are ALL behind the sign". That is extremely weak in many ways. Especially if you Know the distance between Wiegman and Sitzman. If you substituted a Bill Board for the Thornton Sign, that bill board would Not stretch from Wiegman to Sitzman. That bill board would Not be wide enough to obscure both Sitzman and Wiegman. Again familiarize yourself with who was where, along with the 11/22/63 position of the Knoll landmarks. Especially: (1) the Light Post, (2) the Stemmons Sign, and, (3) the Thornton Sign.
