Problems of the Lateral X-ray No. 2

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.
The prosectors and the subsequent medical panels agreed that the head shot entered just to the right of the midline. This location ensures that the perpendicular to the entry site lies practically in the plane of view shown on the lateral x-ray. Further all parties agreed that the major axis of the scalp wound nearly aligned with the long axis of the head. This alignment placed the entering bullet in a parasagittal plane. These fortuitous circumstances permit calculating the incidence angle of the bullet from the lateral X-ray.
The red line represents the trajectory and the perpendicular to the entry site is shown as a white line. By definition the angle between these lines is the incidence angle. Measurements yield 38 degree.
Analysts relate the dimensions of an elliptical wound to the incidence.angle. In particular the cosine of the incidence angle equals the length of the minor axis of the ellipse divided by length of its major axis. The red ellipse shows the shape of the wound that corresponds to the position and direction of the fragment trail shown on the lateral X-ray.
By contrast, the green ellipse represents the shape of the scalp wound based upon the 6 mm. By 15 mm. dimensions reported by Humes and the Clark Panel. The green line makes a corresponding 66-degree angle of incidence with the perpendicular.
The medical panelists offered no explanation for the misalignment between the direction of the inshoot as required by the dimensions of the wound and the direction of the fragment trail.
