There are a nunber of suspicious people, to my mind, that are seen behind the president's car and on the Zapruder film. The first of these is shown below, from frames z230 and z233. The figure in light blue, with a black bib (?), seems to level a gun at the president's car, just as if he is firing, then put that possible gun down, and put his left hand behind his back. The other person seen, just behind, seems to not change his posture at all, and is presumably therefore an accomplice - or has he got a gun as well?
The next group of figures seem innocuous. The man in white is apparently called Charles Brehm, and seems to be clapping. The young man to his right seems to be gesticulating at one point, and to my mind not in a good way. The figure behind is blurred, but is more detailed in other films from behind. I believe that she is the so-called Babushka lady, as named by people who have studied the assassination, and does indeed seem to be taking photographs. She has never come forward or been identified. (If I am right in saying that the figure in blue didn't take photographs but rather is wielding a gun, then this person must have taken the so-called Moorman photo - and somehow 'given' it to Mary Moorman.)
The next people to come into the Zapruder film, and the two that I started off being very suspicious about, are the ones that I call the figure in red, and the figure in blue; - and not Jean Hill and Mary Moorman, as they have been thought to be. (See elsewhere on the website for more about these figures). There is a sound track to the 'French' version of the Zapruder clip, but I am told by an expert in the field of audio investigations into gunshots that the cine camera that Mr Zapruder used had no audio - so there is something of a mystery here.
There should be a link to various youtube films below, one from in front of the figures (Zapruder), and two from behind the figures, (Muchmore, Nix)...
Thanks are due to Johnny Apfelseen for making available this clip/version of the Zapruder film, and this is at the following link... (The FRENCH Zapruder Film version 2012 stabilized slow Mo JFK)
Thanks are due to 'JFK Assassination Truth' for making available this clip/version of the Marie Muchmore film, and this is at the following link. This is a view from behind of these two figures, and note: the very tense attitude of both figures, and of the right arm especially of the figure in red.

Thanks are due to 'JFK Assassination Truth' for making available this clip/version of the Orville Nix film, and this is at the following link. This is a view from behind of these two figures, which are only seen very briefly and only really of the figure in blue. (JFK Assassination – The Orville Nix Film)
