You're spinning like a top.
JFK clutched at his chest and neck before disappearing behind the sign in Zapruder ?
If you are interested in discussing this in an adult way, you can dispense with the emojis and try arguing based on the evidence.
I am not sure whether JFK had started reacting before disappearing behind the sign, although the HSCA photographic panel concluded that he had (1 HSCA 46):
"By Zapruder frame 207, when President Kennedy is seen going behind a sign that obstructed Zapruder's view, he appears to be reacting to a severe external stimulus. This reaction is first indicated in the vicinity of frame 200 of the Zapruder film. The President's right hand freezes in the midst of a waving motion, followed by a rapid leftward movement of his head. (43) There is, therefore, photographic evidence of a shot striking the President by this time."
Perhaps you may wish to explain, by referring to the evidence, why such a conclusion merits a chuckle emoji...
I know you're not claiming that JBC was hit in the back by the first shot, you're just claiming he was shot in the thigh and didn't feel it.
It is not uncommon for soldiers to receive extremity wounds and not realize it for much longer than 4 seconds. A bullet acts so quickly that nerves are destroyed before they can send any signal. If the wound does not interfere with function and causes no pain, why do you think he would feel it? Connally said he never felt the thigh wound and he certainly received it.
The first bullet striking JFK and causing JBC's thigh wound is, arguably, a much better fit with the evidence than CE399 doing all the damage to his wrist and deflecting around the point of contact on the back of the radius to make a left turn to the thigh and end up as it did. Not to mention the problem that Greer said he heard a concussion from the second shot and Tague said he was hit on the second shot. Oh, and I won't bother to mention the 40+ witnesses who said the second shot was well after the midpoint between 1 and 3....
