In the Zapruder still you posted, I see a 4 inch disk of bone hanging down on the right, doubling the apparent size of the wound (the wound and the bone below it), and a lot of blood and tissue on Kennedy’s face.
In the first autopsy picture, it looks like the right side of his temple is gone. In the second, you see a disk of bone everted next to his right temple. The first picture shows what looks like brain all over his hair - it looks like there is a wound in the upper right posterior portion of his head but conceivably there could just be a mess of brains smeared on his hair. The lst picture shows an entrance wound on the lower part of his head, just left of center. His hair has been washed.
The pictures don’t seem inconsistant to me.
If there was an Establishment conpiracy to kill him, they could keep it simple - one deadly sniper, no need to fudge with autopsy pictures. Throw in Oswald as the fall guy if you want, but multiple shooters would be a foolish complication on the part of the conspirators.

You are right Mrs. VS. The other shooters would have just increased the number of shooting signatures and increased the Murphy’s Law factor.
The Carcano and Oswald were capable and could have fired the three shots in the time frame. The distances involved were very modest. The multi-shooter theorists always give the distances in feet instead of yards to make it seem that Oswald made longer shots. But the 2nd and 3rd shots (hits) were made at less than 66 yards.
Give me a Carcano with a cheapie scope and I’ll get hits on a pie plate-sized target at 200 yards.
CASE CLOSED is still the best book on the subject.
