IMHO, Governor Connally mistakenly assumed after the assassination that the first of Oswald's three shots had hit JFK, the second one had hit only him (JBC), and the third one had hit JFK.
Although he correctly remembered turning his head to his right to see if JFK was all right after hearing the first shot (which a 2020 scientific study has shown occurred half-a-second before Zapruder resumed filming, after a 17-second pause, at Z-133), he didn't realize that he began making this turn at Z-160 and that the reason he wasn't able to "see" JFK's face was because by Z-172, JFK had started raising his right hand to wave to someone and his raised hand therefore blocked JBC's view of JFK's turned-far-to-his-right face.
After talking with his mistaken wife and viewing the Zapruder film, Governor Connally confused his Z-160 turn with the gross turn he made after JFK and he were both hit by CE-399 around Z-224.
This is just silly. This is trying to force a large block of wood into a small round hole. I'm tempted to ask if you're using a bogus AI-generated version of the Zapruder film.
Connally turned to his right twice, once early in the shooting sequence in response to hearing a loud noise, and again when he unmistakably heard the Z186-190 gunshot that hit JFK.
As we can plainly see in the film, and as Connally himself said, Connally was not hit before Z229. After spending hours studying high-quality prints of the film under high magnification, Connally said he was certain he was not hit before Z229, and he chose Z234 as the moment of impact. His surgeons chose Z234-237 as the moment of impact. Starting in Z238, we see Connally's right shoulder slammed downward and a pained expression come over his face, consistent with his repeated statement that the bullet's impact felt like someone hit him hard with a closed fist.
We now know that there was no bullet hole in JFK's tie knot, only a small nick on the left edge. We now know that the slits in the front of JFK's shirt were below the collar, that they had no metallic traces around them, that they had no fabric missing from them, and that they were made by the nurses as they hurriedly cut away his clothing. We also know that the throat wound was
above the collar and tie (see, for example, the documentary
JFK: What the Doctors Saw). No bullet exited JFK's throat. The throat wound was an entrance wound.
We also now know that on the night of the autopsy, the autopsy doctors were absolutely, positively, completely, totally certain that the back wound had no exit point. They established this with prolonged and repeated probing, with fingers and with surgical probes, and even removed the chest organs to facilitate and observe the probing. Med techs could see the end of the probe pushing up against the chest cavity lining.
We also now know that the first draft of the autopsy report said that a fragment from the head shot caused the throat wound.
An analysis of torso x-rays of men the same size as JFK proves there was no path from the back wound to the throat wound without smashing through the spine--not just nicking the edge of T1 or C7 but smashing through the spine.
We have known for many years now that the SBT was only concocted late in the WC's life in an attempt to address "the timing problem" and also the Tague wounding. We also know that even three members of the WC rejected the SBT, and that when some staffers heard about the theory they dismissed it as preposterous.
No FMJ bullet in the history of forensic science has done the damage attributed to CE 399 and still emerged with only 3-4 grains of its substance missing and with its lands and grooves intact. The WC's wound ballistics tests refuted the SBT, as Dr. Joseph Dolce admitted for the 1988 documentary
Reasonable Doubt: The Single-Bullet Theory and the Assassination of John F. Kennedy. You can view the documentary here:
Finally, the most sophisticated, data-intensive SBT trajectory analysis ever done, the 2023 Knott Laboratory analysis, established beyond all doubt that JFK and Connally were never aligned in a way that would have enabled a bullet exiting JFK's throat to hit Connally near his right armpit.
