Mike Orr actually stated that a shot to the back of the head happened first....And I agree. If the autopsy photos are legit [showing a hole just a bit left of center] and the Zapruder image seems to show it forward/back in an blink.
If the autopsy photo was real then it would show a fist-sized gaping hole in the right occipital region of JFK's head. But we don't see that. Instead it shows what they want you to see, which is 1 shot from behind and no hole in the back of his head. I have no idea how they faked the photos, but it was easy enough to do back then. And before they were faking photos they were performing post-mortem surgery.
There may have been a simultaneous shot from behind but I doubt that it struck JFK's head without pushing it forward significantly, unless its forward momentum was counteracted by a shot from the front. However, IMO, there was too much backward motion for that to be the case.
I count 2 near simultaneous shots at appox. Z-312, the first one from the direction of the overpass that entered the right side of JFK's hairline and blew a hole out of the back of his head. This sent his head violently backward.
Files recalls that his shot from the knoll happened a split second after the frontal shot and he claimed to have used a Fireball hand-rifle which shot frangible bullets. His shot caused the right temple to blowout when the bullet exploded in JFK's head.
Consensus was that the driver did hit the brakes...but I would have too if I thought I was driving into an ambush.
No you wouldn't. At least 2 shots had been fired and you knew you were already under attack. Nobody in their right mind would slow the limo to a near stop, turn to look back at JFK and watch him get his head blown off and only then decide to skedaddle outta Dodge. The Turkey Shoot Point was precisely where Greer slowed the limo down to. It was designed to be orthogonal to Files' position at the knoll. There was even a painted marking on the curb across Elm at the exact TSP, which Greer coincidentally nearly stopped at. Greer must have skimmed over the SS manual re what to do when the POTUS is under attack.
I also think Umbrella Man and the "Cuban" next to him were signal guys and would like to what Files said about them [if anything]...Not that I completely believe Files either.
Umbrella man and Co. were definitely signalling that JFK was still alive and the Turkey Shoot was on. And sure Files could be BSing, but he seems to know some interesting details about the shooting. Maybe he's stolen the real shooter's story, who knows? But he is by far the best candidate for the knoll shooter, if you believe there was one.
