Was Hickey's AR15 in burst mode?

[Marjan Rynkiewicz]

Here in the Altgens-6 (at Z255) we can see (once again) what is needed for Hickey to swing the AR15 over O'Donnell's head at Z313 etc, relative to the needed trajekt for the headshot -- & relative to the needed trajekt to dent the chrome trim. 
The black star shows the pozzy of the center of the AR15 – the center of the AR15 (black star) is shown on the centerline of Queen Mary, ie halfway between Power's left eye & O'Donnell's right eye.
The horizontal black line from the black star shows the needed level of the AR15 -- it is a little above Hickey's chin (as per all of my other drawings etc in this thread).

Hickey either remained seated (ie hi up half sitting half standing on 2 leather cases on the backseat)(one for AR15)(one for ammo), in which case he had to lift & swing the AR15 hi up over O'Donnell's head, ie above his chin height, at which time he accidentally fired an autoburst of at least 4 shots (the last shot being at Z312)......
......... &/or Hickey tried to stand erect, in which case the AR15 might have been somewhere  below chin height........
......... Bronson frame B07 (my numbering) shows that Hickey elevated hizself about a half head (5"), in which case the AR15 needed to be say 1" above his chest (nipple)(ie to achieve the height of the black star in my drawing).

Gayle Newman said that she reckoned that the sound of the shot at Z313 was directly behind her. As shown in my drawing Gayle would have been near the focus of the echo of Hickey's autoburst offa all of the concrete.

We can add Bill Newman to the list of witnesses who mentioned Hickey holding his AR15 before Z313 (the headshot).
This is a first for any forum – Bill has never been mentioned as an AR15 witness, until today.

………. Well i want to tell u a little trivia if i may…. i recall seeing people with what i want to call a Thompson sub machine gun…. or some type of a rifle about so long [shows about 3ft]…. & it  seemed like it came from the car that was following…. it seemed like they reached behind like the cab of the ? convertible…. u know, they reached into there & came out with a weapon & ran up the grassy knoll…. U FEEL U SAW THIS?.... yes…. but nowhere has this been proved that i'm aware of…. but i had.. i told this to people…. & its been said that the secret service didn’t leave the car…. so maybe it was some other branch of law enforcement…. but i recall what i think…. was about 30yrs ago…. but i recall seeing someone run up the u know with firearms & not a pistol…. something other than a pistol…………….
Bill then mentions the JFK limo slowing… & then mentions a SSA climbing aboard the JFK limo…. & the JFK limo accelerating away.

Bill Newman has clearly erred re a SSA or two running up to the grassy knoll with a machine gun.
But the main thing arising from his wordage is that at least one SSA in Queen Mary picked up a machine gun or similar.
And, clearly, he infers that this picking up of a machine gun happened early on in the saga.  This makes sense. Early on, Bill would be able to see the JFK limo & Queen Mary both approaching – whereas at about Z313 Bill would be looking at JFK, hence Queen Mary (the followup car) & Hickey would be out of his view (ie too far left) -- & after Z313 the JFK limo accelerates ahead leaving Queen Mary momentarily a long long way behind (the Bell film shows Queen Mary  3 lengths behind ie 62ft behind at Z419 which is 5.8 seconds after Z313), so, once again, Bill would not notice Hickey for the first few seconds after Z313 while Bill was focused on JFK, koz Queen Mary is being left well behind.

Bill says that nowhere has this been proved.
Here he probably means that there has been no official mention of a machine gun or machine guns on the grassy knoll.
However, we all know that the existence of or the picking up of an AR15 (or machine gun)(or rifle) by Hickey (or others) was mentioned by a number of witnesses in a number of official sources in November 1963 & in later years.

And we all know that Hickey picked up his AR15 before Z313 koz we all know that SSA Bennett said that after Oswald's shot (this would be Oswald's shot-2 at Z218) Bennett grabbed for the AR15 on the floor & it was not there. 
Anyhow, now we have Bill Newman confirming Bennett's statement re the timing of Hickey picking up his AR15 before Z313 (apart from all of the other such confirmations by others).

Here are 2 gifs of the Bell footage that i made in Jan 2023.

Mr. DULLES. Could you see the President’s car when you looked back?
Mr. LAWSON. Not that first time. As I looked back I looked right straight and saw the grassy median. Then the second and third shots, reports, I noticed the President’s car back there, but I also noticed right after the reports an agent standing up with an automatic weapon in his hand, and the first thing that flashed through my mind, this was the only weapon I had seen, was that he had fired because this was the only weapon I had seen up to that time.

SSA Lawson's WC testimony is interesting. He said that an agent (Hickey) was standing & holding the AR15.
My gif of Hickey shows Hickey sitting hi up (on 2 leather cases), holding the AR15, not standing. So, Lawson must have seen Hickey standing well before my gif starts.
We know that Hickey stood up at about Z300, & fell forward when Queen Mary braked, & accidentally squeezed the trigger, firing an autoburst of at least 4 shots, the last being at Z312 (which hit JFK in the head), & then fell back onto his hi-seat (2 leather cases, a small one on a large one, placed on the seat)

Lawson could not have seen the AR15 in Hickey's hands during my gif (of Bell's frames), koz Hickey is too low, or at least the AR15 is too low, ie it is obscured by the windshield & the upturned vizors & the passengers.
In the first frame of my gif we see Hickey already turned to his right, or a bit past right, ie about 110 deg.
And, during my gif, Hickey gradually turns further right, ie further away from Lawson (who is in the right front passenger seat of the lead car which is almost stopped under the TUP).

But, the above duznt make much sense.
If Lawson saw Hickey standing, then Lawson would have seen Hickey falling & shooting.
But praps Hickey stood up again, & then sat down again, just before my gif starts.
I wont get much sleep tonite.

A close up of my Bell gif of Hickey & AR15 -- & a faster version.

Here is my latest drawing of the Z313 AR15 shot cracking the windshield.
As shown Hickey's shot was at 4 deg relative to Elm St (Elm St is shown level in the drawing for simplicity)(the grade of Elms St was actually about 3.3 deg [needs checking]). The (small hollow point)(ie what was left of it) slug veered in JFK's head & cracked the windshield.
As shown Oswald's fake shot-3 (Oswald fired only 2 shots) would have been at 12 deg relative to Elm St.  The large remnant FMJ slug would have to have veered a long way to crack the windshield (ie impossible) -- & the large (tumbling) slug would have made a giant hole through the windshield (but there was no hole)(just a crack).

............................ SSA Landis saw the cracked windshield....... quote below is from his book........... a small crack, not a hole ........
I heard ATSAIC Roberts and ASAIC Kellerman discussing assignments. It was imperative now to protect Vice President
Johnson, even though he had his own security team. Roberts was sending SA Ready and the rest of his shift to cover Vice President and Mrs. Johnson. I knew these instructions did not include me. My place was with the First Lady. Without hesitation, I continued to run around the rear of the follow-up car and raced to the president’s limo. Clint had already slid off the trunk of SS-100-X and had gone around to the right side of the limo to assist with the removal of President Kennedy’s body.

When I reached the car, Mrs. Kennedy was seated sideways with her back toward me and the left rear door. She was holding what was left of the president’s head in her lap, bending over trying to cover it. I reached over the side of the closed door, took her gently by the shoulders in an attempt to help her up. I said, “Come on, Mrs. Kennedy, let me help you.”

She wouldn’t budge. I couldn’t see her face, but I heard her say firmly, “No, I want to stay with him.” I let go. Realizing that I needed to do something different to get the First Lady to safety, I grabbed the door handle and yanked the door open.
Just then, Clint arrived and took over. He had come around from behind me and stepped inside the large backseat area ahead of me, past Mrs. Kennedy, closer to the president’s body. The situation was fluid-others were trying to remove the body.

I stepped into the limo behind Clint. I was scanning everything insight. The first thing I noticed was a small splintered crack in the front windshield. It was located to the left of the rearview mirror on the driver’s side. I immediately assumed that it had been made by a ricocheting bullet fragment. How on earth could a bullet fragment have flown up there without hitting someone? I wondered.

Looking up, I saw SA Win Lawson. He was running along the walkway coming toward us, pushing a gurney. He was followed by another person dressed in hospital garb who was also pushing a gurney. Two gurneys, why two gurneys?
