Problems of the Lateral X-ray No. 2 - Part one
Herbert Blenner
At first glance the trail of fragments caught my attention. I fumbled
through my desk grabbed a ruler and a protractor. Not to my surprise,
I fitted a 15-degree angle between the transverse plane of the head
and the trail.

Zapruder film Z-312 shows President Kennedy leaning forward
immediately before the head shot. I measure a 30-degree angle between
the transverse plane of his head and the horizontal.

Clearly any fragments deposited by a bullet with a declination angle
of 15 degree would have crossed the transverse plane of the head at a
15-degree angle but with a sense of rotation opposite of that shown on
the lateral X-ray.
I invite skeptics to follow this argument by geometric construction.
Draw a horizontal line representing the transverse plane of the head
with an anatomical orientation. Construct a line making a 30-degree
clockwise angle with the horizontal to represent the transverse plane
of the head as seen on Z-312. Now draw a dotted line making a 15-
degree clockwise angle with the horizontal. This line represents the
fragment trail. Finally rotate the entire drawing 30-degree
counterclockwise so that the transverse plane of the head becomes
horizontal as seen on the X-ray.

Oh, good! We've got another conspiracy theorist who thinks he can grab
a pencil and a protractor and start drawing lines (with perfect
accuracy) on a 2-dimensional item (in this Herbert Blenner instance,
it's an autopsy X-ray). Lovely.
I wonder how many times Dale Myers has repeated the following basic
rule of photo analysis? Probably thousands. Only for this simple rule
of thumb to be totally ignored (year after year) by kooky conspiracy
theorists:
"In short, you cannot simply draw or overlay lines on a two-
dimensional image and extract three-dimensional information." -- Dale

Herbert, even if I could understand what your challenge is, I wouldn't consider
accepting it--because I'm convinced your so-called "trail" is not a trail...and
there was no entry where you propose there was one. We've been here before and
I've pointed out that the fragments are too spread out in the horizontal plane
for them to represent a trail--FWIW, Mantik pointed that out in "Assassination
Science". OF COURSE, YOU HAD A HEAVY SCIENTIFIC RESPONSE FOR THAT: something
about the spinning bullet would have spread the fragments widely
horizontally...Okay, I can't argue with that explanation because it was and will
still be over my head, but.....
Can you rule out the possibility that those high fragments represent metallic
debris that shed from the bullet when it broke apart as it traveled from its
near EOP entry towards the high coronal suture exit? How?
IMO, What makes that a more likely scenario than your "bullet enters the BOH and
exits the throat" theory includes this logic:
1. There was only one entry in the BOH and it was near the EOP. The replications
of F8 and the trail of tiny opacities seen on the lateral extending from near
the EOP, not to mention the autopsy report, prove this.
2. All the high fragments were so small none were recovered and that's
consistent with the explanation that they were carried upwards along with the
brain matter that exploded up.
3. There was no hole in the floor of the skull to support your throat exit
theory.
4. There was only one channel-like path through the brain reported and it did
not extend from the upper BOH to the lower front part of his brain.
5. The ARRB forensic experts found no evidence whatsoever of a high BOH entry.
6. I don't see how your entry high in the BOH, exit the throat theory reconciles
with the two large fragments found in the front of the limo. Please explain.
7. Mantik scanned the upper BOH with his densitometer and found no hole...just
cracks.
Now, if my recollection of your theory is wrong, I apologize...but there is a
pile of evidence for only one hit to his head and that bullet entered near the
EOP, with the largest framents exiting high in the front just forward of the
coronal suture.

I am comparing a nearly lateral view of President Kennedy's head on
Z-312 with the lateral X-ray No. 2. So the pertinent angles are
essentially in the same plane. This observation justifies my use of a
two-dimensional analysis.
Of course, knowing how angles in a three-dimensional space project
upon a two- dimensional plane enables me to calculate the error in
measurement due to the azimuthal angle between the two nearly lateral
views. This the error equals
sin ( a ) sin ( b ) ( 1 - cos [ c ] ), where a is the lean angle, b is
the declination of the trail and c the azimuthal angle between the two
views.
Each factor in the error expression is less than one, so how do you
explain the two hundred percent error between lateral X-ray No. 2 and
what is required by the lean shown on Z-312?

You can do a least square fit of the fragments seen in the lateral X-ray
and derive the downward slope. To illustrate the slope I superimposed the
X-ray on the Dox drawing and drew in the slope. You'll notice that the
slope is not compatible with either the WC or the HSCA entrance sites. But
it ends up close to the hole in the forehead.

No one claimed to have extracted three-dimensional information.

>>> "No one claimed to have extracted three-dimensional information." <<<
But that's kinda what you HAVE to do (i.e., extract 3D info) to make
the kind of argument Herbert Blenner is trying to make regarding
angles and measurements as seen in JFK's autopsy X-rays.
Duh!

Cut the bull, David. You do not have a clue regarding my argument.
http://mysite.verizon.net/a1eah71/temps/clippedz312.jpg
The white line represents the transverse plane of head while the red
line indicates the plane containing the trajectory of a bullet with a
declination angle of 15 degree.
http://mysite.verizon.net/a1eah71/temps/anatomicalz312.jpg
When the earlier graphic is rotated counterclockwise by 30 degree, the
transverse plane becomes horizontal. This rotation anatomically
orientates the relevant angle of the head. Now the red line containing
the plane of the wound track crosses the transverse plane with a 15-
degree angle with a sense opposite that as shown on the lateral X-
ray.

I didn't even read your argument, Herbert.
I was merely stating that your method of research (i.e., attempting to
draw lines in 3D space while using 2D photos and arrive at accurate
measurements and exacting angles) is simply impossible. And it is
impossible.
