Error in the narration of the motorcade reenactment: The fatal headshot occurred when the limo was about 85 YARDS down the road, not feet. Sheez.
Please note that Tina Towner told Max Holland she recollected the limo's not swinging quite so wide as it's depicted coming out of the curve in the reenactment. If true, this would have placed the traffic light's mast arm more directly over JFK (from the assassin's POV) as the limo passed under it.
Also, I think the box FBI Special Agent Joe Howlett is sitting on was actually a bit farther away from the window, making it a perfect "stool" for the assassin to sit on (and lean foward from while monitoring the approach of the motorcade). Regardless, the assassin would have had to stand up to take the first, sharply-downward-angled shot, be it at 1.4 seconds before Z133, or closer to Z133, itself, as Vicki Adam's seems to have suggested to James Leavelle in February of 1964, and many years latter to Barry Ernest.
