How can a missed shot be required if JBC was hit in the back by a different bullet than the one through JFK's neck? We know that JBC and JFK were already hit before z313 so if there was only one other shot that struck, it must have made all the wounds other than the JFK head wound.
Here is how three shots three hits works:
1. The first hit JFK passing through his neck and continued going straight thereafter.
2. The second struck JBC in the back.
3. The third struck JFK in the head
Right, thank you. I don't insist on this scenario - I don't insist on any scenario, because there are just too many variables - but I don't find this implausible at all. The fact that there is, at this late date, so much debate as to how many shots were fired, when they were fired, and from where they were fired is rather telling, I believe.
