Good copies of the Bell Film and the Hughes Film will give you a view of the initial route UP the knoll taken by Officer Haygood. In the Hughes Film after Haygood emerges from behind the Fort Worth sign, you can even see an eyewitness in street clothes heading UP the knoll to the West/Left of The Steps. This sequence in both films was taken amidst the camera cars traveling down Elm St/East of the Triple Underpass, and is allegedly less than 1 minute following the assassination. This would be extremely early for any member of the general public to physically be on that section of the Knoll and moving UP toward the picket fence. I believe this eyewitness is a still unidentified Lone Wolf. As technology improves providing us with relatively Detailed JFK assassination films and photographs, the more it becomes obvious that many pieces to this puzzle are missing.
Hughes yes, thanks, I see it, a couple seconds where he's moving, it's debatable. Would be nice to see it stabilized.
There's no one else up there before Haygood at least I don't see anyone except a tree trunk and there's no evidence of anyone pointing the way for him, Curry's order to get up there could well his only motivation, that and the unusual scene he came upon, strange that he would remember it another way but a cross examination may have helped jog his memory. If Curry gave that order within about 30s IMO Haygood's brave reaction syncs rather nicely, a real shame he didn't make that jump. Shooting happens in the last seconds of 12:30pm I think, Curry's message in 12:31pm, I also think it's about a minute for Haygood to reach the corner so almost 12:32pm(that is of course if you ignore the testimony and just focus on the film etc). Within 3mins he's on the radio talking about a witness who was stood near the TSBD, has to be Jackson.
