That is a huge, in-depth report! I haven't the time to go through it all but I guess what your point is that the Zapruder film wasn't tampered with, wasn't retouched.
In that case, the differences in the state of Kennedy's cranium between the two frames that I posted proves that there were 2 almost simultaneous bullet impacts to the head.
Unless you have a another explanation?
Not cranium being pointed to. Blood-drenched hair or scalp flaps (they're pretty red in the autopsy photos).
The opening of scalp at the top is mostly forward of a line drawn forward of the ear.
The scalp opening reaches up to the top of the head. Kind of interesting how the Zapruder film has the scalp opening in the exact same location as the autopsy photos. Cue the alterationists.
