How unfortunate you can't provide evidence for a first missed shot. Can anybody?
(a) Most of the witnesses (about 90%) thought three shots were fired. More witnesses testified to two shots than to four or more.
(b) About ten witnesses in Dealey Plaza identified one of the upper floors of the TSBD as where they saw a shooter, or a rifle.
(c) On the sixth floor, in the southeastern corner window facing Elm Street, three spent rifle shells were found. From a, b, and c, we can reasonably conclude three shots were fired from that window.
(d) We have evidence of a bullet striking the back of JFK's head and exiting the right top (Zapruder film, autopsy report, autopsy x-rays and photos, and the HSCA pathology review panel).
(e) Two large bullet fragments, most likely from one bullet, comprising the front quarter and the rear quarter of a bullet, were found in the limo by the Secret Service after the shooting. Those two large fragments were ballistically traceable to the rifle found on the sixth floor, to the exclusion of all other shots in the world. That takes care of one of the three shots the witnesses heard.
(f) JFK had a wound in his upper back that exited his throat (autopsy report, and the HSCA pathology review panel).
(g) According to tests by Lattimer and others, the bullet would not have been greatly deformed by this passage but would have started to yaw as it exited JFK's neck.
(h) Seated in front of the President, but slightly to the left and a bit lower than the President, was Governor Connally.
(i) According to on-location tests done in Dealey Plaza, a bullet exiting JFK's throat on a downward trajectory from the sixth floor had to have struck something in the limo in front of JFK. There was no damage to the seat back or seat, however John Connally was struck at approximately the same time.
(j) Connally's wound in his back was elongated, which would be explained by a yawing bullet.
(k) Connally suffered a wound through his trunk, a wound through his wrist, and a wound in his thigh. It was the judgment of his primary physician that all those wounds could have been caused by one bullet.
(l) No bullet was found in Connally, only minutes fragments in his wrist. A nearly whole bullet was found at Parkland Hospital on a different floor from where the Governor was being treated. It was found on one of two stretchers, one of which had nothing to do with a shooting, and the other of which happened to be the Governor's. This takes care of the second bullet.
(m) There appears to be a bullet missing, hence a missed shot.
The Warren Commission did not decide which shot missed, because the Zapruder film is without sound, and the witnesses disagreed on the exact sequence of events.
They provided three scenarios, a first shot miss, a second shot miss, and a third shot miss.

It appears you object to the first shot miss scenario, but you don't tell us specifically why, or which shot you think missed.
Can you do that now?
