Nellie Connally and Jackie both stated that the first shot hit both men, referencing when JBC cried out Oh No No No, which Gov Connally stated he cried out when he was hit.
I'm sorry, but that's just comical. It is well known that Jackie Kennedy did not believe the single-bullet theory, and it is especially well known that Nellie Connally didn't buy the theory. Let's read Nellie's testimony. She said she heard a noise, that she saw Kennedy reach for his neck, and that Gov. Connally was in the process of turning around to look at Kennedy when "the second shot was fired and hit him":
I heard a noise that I didn't think of as a gunshot. I just heard a disturbing noise and turned to my right from where I thought the noise had come and looked in the back and saw the President clutch his neck with both hands.
He said nothing. He just sort of slumped down in the seat. John had turned to his right also when we heard that first noise and shouted, "no, no, no," and in the process of turning back around so that he could look back and see the President--I don't think he could see him when he turned to his right--the second shot was fired and hit him.
So Nellie Connally most certainly did not say that JFK and her husband were hit by the same shot. And, of course, Gov. Connally himself insisted that he was not hit until Z234, and, after all, he was the one who experienced the hit. He looked at high-quality blowups of the Zapruder film at
Life magazine and was adamant that he was not hit by Z224 and that Z234 was the frame of impact of the bullet that hit him.
In defending the idea that the shirt bunched in nearly perfect correspondence with the coat, someone else said (I'm paraphrasing),"We don't know what was going on with the shirt under the coat." Well, true. We don't
know, but, gosh can't we use some
common sense? When JFK was hit in the back, most of his back was reclined against the seat. Given the nearly perfect alignment of the coat and shirt holes, the shirt would have had to almost perfectly duplicate the bunching of the coat, both vertically and horizontally. You do not have to be a scientist to know that such a scenario is wildly implausible.
Furthermore, I see that SBT defenders are still ignoring the fact that the coat and shirt would have had to bunch from T3 up to and over C7/T1. Just any modest bunching anywhere on the coat will not work. It has to be bunching that would pull the part of the coat that was over T3 and move it to be over C7/T1. The modest bunching that we see in some photos/frames in JFK's coat just before the shot to his back does not even come close to doing that.
Below is a graphic to give you some idea of the vertical difference between a wound at T3 and a wound at C7/T1. The graphic also shows how far down a T3 wound would be based on the white dot that was placed on the back of stand-ins to represent the location of the hole in JFK's coat in some WC reenactments (since the graphic is large, you'll need to scroll over to see the reenactment photos--or you can just click on the link to open the photo in a new window).
