Thanks for providing the links. They show the 2 women standing near the lamp post far better than SA Hickey. I think you are seeing what you want to see with respect to Hickey.
For sure its very blurry. I wish i had the superior 2019 copy/frames.
In the end i had to explain how Hickey managed to shoot & then fall/sit in just 2 Zapruder frames after Z312/313.
And the key problem woz uzing the footfalls of the white shoes of the lady on the grass to try to establish simultanaety of the Bronson footage with the Zapruder footage.
Critics said that Hickey woz sitting at Z313. I sayd that my analysis showed that Hickey woz sitting at Z315.
But in any case my analysis showed that Hickey could hav fired that autoburst without needing to rize much from hiz allready hi sitting pozzy on the 2 leather cases on the backseat. So, the rize needed woz less than say half a head.
