First, let me thank you again for your kind words, and commend you for
having the integrity to confirm what others of your belief, refuse to do.

But as I'm sure you expected, I must take issue with your claim that the
cause of that skull piece flipping to the rear was something other than a
second headshot. This is in reply to your previous post:

My sincerest hope is that having confirmed that I am at least partially
right about this, you might respect my analysis enough to consider the
evidence which convinced me that this the result of a gunshot. First, I
would direct you to this image:

Notice that by frame 317, the explosion has completely subsided.
Obviously, that piece of skull has not yet flipped, nor has it begun to.

Also, please notice the hair toward the front of the head at which I point
with a superimposed, blue arrow.

The image to the left is of frame 337. Notice that the hair we saw at 317,
toward the front of the head, has been displaced and is now part of a
brown colored layer, behind and just above the indention where that skull
piece used to be.

The point of all this is, that whatever the force was that caused that
skull piece to flip, had to have been substantial enough to rip out and
displace hair and scalp. It has to have been substantial.

Since the explosion seems to have dissipated by 317, I don't see how that
could have been the cause.

I considered that the momentum of JFK's head moving "back and to the left"
might have been great enough to have been the cause. But as I examined
that motion in the Zapruder film, I discovered that as the head reversed
direction (probably due to the jet effect that Alvarez described), it
really didn't go back very far. In fact, the head never went all to the
back of the seat. It actually only traveled about 2 feet during the seven
frames in which there was rearward motion.

By my calculation, the head was moving then, at a velocity of less than 4
mph. Of course, the explosion at 313 generated force that was vastly
greater than that of JFK's backward movement.

Perhaps you can suggest a better alternative, but I cannot think of any
other force at that time which could have caused the "flip", other than a
gunshot.
