Of course, another key fact about the white patch is that it covers a good part of the area that over 40 witnesses said was missing.
The white patch may also have been put there to conceal the low fragment trail described in the autopsy report. The autopsy doctors described a trail of fragments that went from the EOP entry site to a point just above the right eye. No such fragment trail appears on the extant x-rays.
The only fragment trail visible on the x-rays is the one several inches higher near the top of the skull. We are asked to believe that the autopsy doctors not only mislocated the rear head entry wound by a staggering 4 inches but mistook a fragment trail at the top of the head for a trail that began at the EOP and went to the right eye.
Of course, also asked to believe that the autopsy doctors did not notice the most obvious apparent bullet fragment on the skull x-rays: the 6.5 mm object. Or, we are asked to believe that they saw it but for some reason did not remove it and omitted it from the autopsy report. As most here know, the 6.5 mm object has now been determined by optical density measurements to be a forged image ghosted over a much smaller actual fragment. Dr. Mantik has even be able to duplicate how the forgery was done.
