The Shifting Single-Bullet Theory--It Always "Works" No Matter What

[Martin Weidmann]

Again, thanks for watching.

Exactly, if it looked to be altered, this fact would stick out like a sore thumb, even to the casual viewer.

Precisely, so why alter it at all, what could that possibly achieve? Because for some reason Griffith thought it was of vital importance to alter Brehm's son, because most likely Griffith believes Brehm's son was another assassin?
The film shows to the casual uninformed viewer that Kennedy goes back and to the left, so why wouldn't "they" alter this most crucial aspect in the Film?

Again, thanks for watching.

Unlike you, I give people the benefit of the doubt.

If there  is some question of alteration of the Z film , which means frames being removed or added? Then I must ask why then did not the conspirators do a better job of editing so that the MC rifle shots would appear to be spread over 6-7 seconds rather than what the Z film as we have been presented shows as only a 4.8 sec spread between Z224 reactions of JFK and JC and the Z 313 last shot?
 
There is something which SEEMs peculiar about the head shot blood spray disappearing in only one frame (1/18th of a second ).

I’m not sure this quick dissipation was ever replicated by the 2003 Beyond Conspiracy documentary , however , they did manage to replicate the forward ejection of brain matter.

It’s the Z312–Z313 frames which show a 1/18th sec forward movement of JFKs head that would probably be the frames that were altered because without that little detail, the general perception of   the public would be (as it was at first public viewing of the Z film) that the “back and to the left” movement of JFKs head was a clear indication the head shot came from the front of the limo.

1. Yes, even though removing even 1 frame would be painfully obvious, let's ignore that for a moment and consider that any removal of frames means a shorter time between shots and that's not going to go well when your assassin has a bolt action rifle.

2. This hunting video shows that blood mist dissipates quite quickly. There was strong breeze blowing up Elm street and then remember that the resolution of the Zapruder film at that magnification was relatively poor.



Later frames do show particles in the air which would have struck Hargis and the the Queen Mary. But as you can see in this higher quality blow-up, the size of the film grain hinders any closer examination of these small particles. But what is clear is the right side frontal open wound above the right ear and the subsequent hinged bone flap.



The area we are talking about is a fraction of a millimeter, much, much smaller than the size of a pin-head. Note, Zapruder frame flipped to suit 8mm background graphic.



3. Agreed, Kennedy's head initially goes forward and if anything, this would be the first and only place for alteration. But those silly conspirators!

I guess you haven't read most of my replies herein. JFK starts reacting long before Z224, as the HSCA PEP noted, as we know the WC's experts recognized, and as Olson and Turner noted, etc., etc.

In wound ballistics tests, the particulate spray from head shots remains visible for at least six frames, which only makes sense when you think about it. Another problem with the spray in the Zapruder film is that no spray blows backward, yet we know that blood and brain were splattered on the trunk, on the follow-up car, and on the two left-trailing patrolmen. Hargis was hit so hard by the spray that he thought he himself had been hit (and he was only moving about 11 mph, and the film shows no spray into which he could have driven of that could have hit him).

The Z312 forward head movement is highly debatable. I've cited it because WC apologists cited it for years after Dr. Alvarez detected it. Subsequent research has found sound reasons to believe that the movement is an optical illusion. A much more obvious and faster forward movement occurs from Z328-330. A gunshot impulse on the Dallas dictabelt recording occurs at right around Z328. For mor info on this, see British research Martin Hay's review of Josiah Thompson's 2021 book Last Second in Dallas: https://www.kennedysandking.com/john-f-kennedy-reviews/last-second-in-dallas-by-josiah-thompson.

I notice that WC apologists seem reluctant to deal with the Knott Laboratory refutation of the SBT mentioned and documented in the OP. Knott Lab, a forensic engineering and animation lab, has proved that Connally's position and back wound make the SBT impossible. Knott Lab engineers conducted a laser test in Dealey Plaza, collecting millions of data points, converted the data into 3D imagery, and determined that the SBT is impossible because Connally's back wound does not and cannot align with a bullet fired from the sixth-floor window and exiting JFK's throat. Here's a video on the Knott Lab study:

Why the 'Single Bullet Theory' in JFK Assassination Is Impossible

As I noted in the OP, the video has already had nearly half a million views since being posted about a month ago.

Of course, Dr. Mantik destroyed the SBT back in the 1990s when he produced an overhead scan of a man with dimensions closely resembling JFK's dimensions and showed that any bullet going from the back wound to the throat wound would have had to smash through the spine. WC apologists are still in denial about this powerful evidence. They've produced goofy graphics that move the back wound in order to enable the bullet to miss the spine.

Ok. Firstly, jfk was leaning right or at least he was hard right against the side of the limo.
Nextly, jfk had his right arm up high, ie waving.
Nextly, when hit, at Z218, jfk was looking to his left (ie had his head turned left), towards an african american family (dad mum & kid), standing on the grass on the south side of Elm St (the only humans anywhere near that location).
The SBT works perfectly, allways did, allways will.

Just like Mantik's misrepresentation of the stereoscopic back of head autopsy photos, he's again wrong here.

Here's an article on the Knott Laboratory SBT analysis published in Forensic Magazine ("Forensic Animation Firm Tests 'Single Bullet Theory' in Reconstruction of JFK Assassination":

Knott Laboratory, an industry leader in forensic engineering and animation for more than 40 years, was commissioned to create the digital reconstruction of the assassination of President John F. Kennedy to test the "single bullet theory" from the historic Warren Commission report. They have released their findings in advance of the 60th anniversary of the assassination of President Kennedy.

Kennedy was famously assassinated on November 22, 1963 in Dealey Plaza in Dallas, TX. The Warren Commission was assembled to investigate the shooting and issued a report in 1964 finding that Lee Harvey Oswald was the lone gunman, firing a total of three shots in the incident. However, evidence suggests the potential of a fourth shot from another location indicating a second gunman and a wider conspiracy to kill the president.

Knott Laboratory was hired by John Orr, a former Justice Department attorney, who conducted his own investigation as a private citizen, making trips to the National Archives to review every document available, and even being permitted to examine original evidence such as the president’s shirt. In 1995, Orr sent his report to then Attorney General Janet Reno, which did achieve some reexamination of the evidence by the FBI, but ultimately didn’t lead to anything new or conclusive. Once Orr hired Knott in 2018, modern science was able to corroborate his theory.

The "single bullet theory" concluded that one of the three shots fired from the window by Oswald struck both President Kennedy and Governor Connally. The report stated that the bullet hit Kennedy in the back, exited his neck, entered Governor Connally in the right armpit, exited his chest, went through his right wrist and embedded in his left thigh.

To reconstruct the scene with modern technology, the Knott Laboratory experts conducted a high-definition laser scan of Dealey Plaza to generate a point cloud of up to two million points per second, to accurately measure point-to-point anywhere in the scene. Knott Laboratory also obtained historic photographic evidence from the plaza, the limousine, and the "Zapruder film," which is widely known as the best video footage of the incident in its entirety.

From this point cloud, the team of forensic engineers was able to match images from the scene and the Zapruder film using a process called photogrammetry. They modeled the presidential limousine using multiple photographs and established the correct dimensions of the vehicle. Through a process called match moving, they synced frames from the Zapruder film into the digital recreation of the scene. The match moving enabled the alignment of the digital models of Kennedy and Connally in the vehicle to establish their positions frame by frame throughout the incident.

“With the ability to measure distances, locations and angles from the point cloud, we could develop the exact trajectory between Oswald's shooting position and points on each body,” said Stanley Stoll, CEO & Principal Engineer of Knott Laboratory. “Our team tested bullet trajectories using the two frames from the Zapruder film where the first shots occurred and the known entry and exit points on Kennedy and Connally.”

Stoll continued, “The shooting position, bullet exit point on President Kennedy, and entry point on Governor Connally should all be reasonably in line. When drawing this line from the sixth floor perch of the Texas Book Depository to the positions of the two men and their entry/exit points, we found a significant angle difference. This case is ongoing, but evidence strongly suggests there is more to the story in this historic event. Modern science refutes the Warren Commission’s findings on the assassination of President John F. Kennedy.” (https://www.forensicmag.com/608244-Forensic-Animation-Firm-Tests-Single-Bullet-Theory-in-Reconstruction-of-JFK-Assassination/)
