Given the alignment of JBC and JFK in the car and the use of jacketed military ammunition, how do you explain the location and trajectory of the elliptical wound in JBC's back if the bullet does not first pass through JFK?
An elliptical wound is made by a non-tumbling bullet striking nose first at an angle. It cannot be made by a tumbling bullet. An ellipse is a symmetrical shape.
A tumbling bullet makes an asymmetrical shape that looks either like the side profile of the bullet or is ovoid ie. egg-shaped (rounded at both ends but more pointed at one end than the other).
Dr. Shaw said the wound was "elliptical" not "ovoid". Dr. Shaw made a point of noting that the bullet made a "tunneling" path through JBC. That is consistent with a non-tumbling bullet and inconsistent with a tumbling bullet.
This just another example of the twisting of facts that proponents of the SBT make.
