It is somewhat inevitable that the discussion would come to the dynamics of Kennedy’s injuries, which I dislike going over, because it is gruesome. Nonetheless, this is a persistent misconception, so I will address it here.
Buffs frequently claim that Kennedy must have been shot from the front, because in the Zapruder film the President visibly jerks backward—head and body—after being shot in the cranium at Z-313. This is provably false on a number of points.
First, as Mr. Bleshfuck so crudely alludes to, “Newtonian physics” dictates that for every action there is an equal and opposite reaction. Any bullet that could impart enough energy to hurl its victim backwards would produce a recoil strong enough to throw the gunman back with equal force. As I am sure he’s aware, no small arm on planet Earth is capable of this. In the real world when people are shot, whether with handguns or rifles, they are not bodily knocked back. This is empirically borne out everywhere and universally known to wound ballistics experts. To expect otherwise is 80s action movie physics.
Secondly, between Z-312 and Z-313, it is plainly visible in frame-by-frame viewing that the President’s head moves slightly, but unambiguously, forward as the bullet enters his skull and explodes out. As I said, no bullet in existence can move an entire adult’s body in the manner of Kennedy’s backward lurch, but a small and comparatively light body part like the head can be, and is, moved by the energy imparted by a rifle round. This abrupt jerk forward of about 5cm, coming before the dramatic convulsion backward, is further confirmation that the head shot necessarily came from behind.
So why was the President thrown back? There is one major reason, which is neuromuscular trauma. The violent and near-instantaneous decerebration caused by the Carcano bullet provoked a massive neurological spasm across JFK’s body. As his spinal cord was mechanically stimulated by the shockwave and its motor neurons fired in unison, this resulted in the concurrent extension of all Kennedy’s skeletal muscles. In such an event, the back muscles, which are the strongest in the torso, predominate, and that is exactly what we see happen in the Zapruder film. In rather gruesome experiments performed by shooting anesthetized goats with rifles, Dr. Alfred Olivier was able to experimentally reproduce exactly this reaction. Physicians have long been aware of the abnormal posture that is caused by grievous cerebral damage, in which the muscles of the body are extended and the neck is craned back. Kennedy assumed this decerebrate posture swiftly and violently, in keeping with the swift and violent nature of his injury.
A secondary reason is the so-called “jet effect.” As the bullet fragments exited Kennedy’s skull, along with them came several substantial fragments of bone, and the better part of the right hemisphere of his brain. The upshot of this was analogous to a rocket’s exhaust gases producing thrust along the opposite vector of the ejecta. Nobel Prize-winning physicist Luis Alvarez and physician Dr. John Lattimer were able to reproduce this phenomenon, first with melons, then with human skulls, finding that under appropriate conditions, they will in fact move towards the rifle when shot. Again, Newtonian physics, faggot.
Anyone who is interested in the physical and anatomical factors at play in the JFK assassination is encouraged to check out the physics article here https://www.heliyon.com/article/e00603/ , which, in addition to being a quite thorough overview, deploys some sophisticated mathematical modeling to help explain what is going on.
Finally, as for the frankly incredible, but occasionally repeated claim that JFK’s body was surgically altered between Dallas and the autopsy, I simply observe that from the time it was placed and hermetically sealed in the casket until its arrival at Bethesda, it was constantly attended to by Jackie Kennedy, Brigadier General Godfrey McHugh, and Secret Service agent Richard Johnsen, not to mention the small army of JFK’s aides and staff. Moreover, upon loading, steel cables were placed around the casket to prevent it or its lid from shifting during the flight. Removing these cables and then replacing them would have been a practical impossibility for the conspirators in the narrow time window available. I doubt these bare facts will placate some buffs, who are doubtless capable of constructing a yet more wild and implausible scenario for the theft of the body. I merely note that the reason they raise this issue in the first place is that the evidence provided by the X-rays and autopsy so strongly demonstrates two shots from behind, and is so devastating to any alternative scenario of additional or different wounds, that buffs are cornered into claiming they are somehow illegitimate. Finally, I express my bemusement at Bleshfuck’s claim that “a chunk out of Kennedy’s face” was altered, as his face is clearly undamaged in the autopsy photographs, and such an odd wound would produce no corroborating evidence for the lone gunman theory—on the contrary, it would represent a significant complication for it.
