Ever wonder why the hardcore CT's try to create doubt about the Zapruder Film?

Frame 337.
I've drawn in a red outline to highlight the state of JFK's head at this point.
Earlier frames show skull and brain matter being blown out of the top of JFK's head.
The image above shows a massive crater in the top of his head.

Right, so what do you make of this:

I've already answered this question.
Look at Jackie's face, there's no features. The frame is really blurry so it's difficult to make a proper assessment.

No, you haven't answered the question. Blurring merely masks the detail of a surface. It doesn't create or extend zones on tone/matter. Despite the lack of sharp definition, we can clearly see in the frame that the upper cranium area, a good 6" above the right ear is intact. A few frames later, it's no longer there.
So again, how would you explain what we see?

  Were the photos above taken Before Or After Humes took the bone saw to the top of JFK's head? Be careful now. The aging Humes documented in his ARRB Testimony that he saw the body of JFK arrive at Bethesda BEFORE the hearse carrying Jackie and the ceremonial casket arrived there.

Jerry seems to have it covered.
Have you ever read the Zavada report?

[Jim Hawthorn]

So this is another thing you haven't mapped, Jim?
The missing scalp at the top begins in front of the ear, just like it's shown in clear frames like Z317, Z323, Z335 and so on.
Allowing for the changing lines-of-sight in the latter frames, I see no difference in the relationship of the head wound features.

Then how do you explain this image, with the upper cranium absent?

[Jim Hawthorn]

Have you ever read the Zavada report?

No Dan. Could you point me to it please?

[Dan O'meara]

No Dan. Could you point me to it please?

This is the version I use:

https://archive.org/details/ZavadaReport

It's the most comprehensive examination of the film possible, made by one of the team leaders of the team that invented the film Zapruder used.
Zavada was considered the world's leading expert on Kodachrome II at the time of the report.
