The JFK brain matter that contained this trail of fine small particles was not preserved nor were those tiny particles ever removed and examined to see if they could be matched to 6.5 mm MC ammo. Just coincidence?
Ditto for the 6.3 x 2.5 mm fragment in the rear outer table of the skull visible on the lateral x-rays. The autopsy doctors could not have missed this fragment, but they ignored it because they knew they couldn't associate it with the rear head entry wound. Sibert and O'Neill noted the fragment in their report on the autopsy, but Humes said nothing about it in the autopsy report.
The fragment is 9 cm above the rear head entry wound in the occiput and 1 cm below the phantom cowlick entry wound above the lambda in the parietal bone. The fragment doesn't fit with either entry site. Dr. Russell Fisher told Howard Donahue that he and the other Clark Panel members believed the fragment was a ricochet fragment. That is the only rational, scientifically plausible explanation.
For many years, WC defenders gleefully cited Dr. Vincent Guinn's 1977 NAA test. Guinn claimed that the test results showed that five JFKA bullet fragments came from just two bullets and that those two bullets came from the same batch of bullets that Oswald allegedly used, which in turn seemed to constitute conclusive scientific evidence for the single-bullet theory. However, Guinn's NAA claims were destroyed 20 years ago, first in 2006 by scientists Erik Randich and Patrick Grant, and again in 2007 by scientists Cliff Spiegelman, William Tobin, William James, Simon Sheather, and D. Max Roundhill.
This was, and remains, historic because if the five fragments came from three or more bullets, instead of just two, that would mean a second gunman's bullet must have hit JFK, as the scientists themselves explained.
So convincing were the refutations of Guinn's NAA findings that former HSCA chief counsel G. Robert Blakey denounced Guinn's NAA research as "junk science." Blakey had been deeply impressed with Guinn's NAA findings when they were presented to him in 1977. In fact, he leaked them to the press early in 1978 as decisive proof of Oswald's guilt. But, to his credit, when Blakey read the 2006 and 2007 refutations, he repudiated Guinn's NAA claims.
