Doug Horne greatly praises Dr. David Mantik's new JFK Assassination book!

Well, I think you are way, way off base here. I honestly can't fathom what you are looking at in the skull x-rays and head photos. First of all, the overlapping bone does not cover the area that is occupied by the white patch. This isn't even a close call. And, good grief, if the overlapping bone corresponds with the red flap above the ear, how in the world can you believe that it constitutes the white patch? 

Have you replied to Dr. Mantik's response to your critique. Here is some of what he says therein:

       Does the overlapping bone (on the lateral X-ray) explain the “White Patch”?

       No, it does not—nor could it even do so in principle. First, these are two distinctly different areas, as should be obvious from the right lateral X-ray—the White Patch is much more posterior than the overlap area. See my image of the White Patch in [i]Assassination Science[/i] 1998, p. 160, or slide 5 in my Dallas lecture, or my Figure 5 just below. . . .

       In my Figure 2, I have identified the external auditory canal, which Speer ignores; that structural feature clearly locates the external ear—without any ambiguity. Speer also ignores the evidence of the AP X-ray (my Figure 1). Notice there how the wing lies far out in space, quite detached from the skull. On the other hand, if the wing had extended far posteriorly (as Speer wants to believe), then some part of it would be seen much more medially in the AP X-ray, but it is not there. This argument is so powerful that little else need be said. But there is more.

       Second, the ODs of these two areas are quite different: on the right lateral X-ray, the mean OD of the white patch (0.625 ±.055) is almost the same as the petrous bone (0.55), whereas a typical OD (1.33) for the overlap site is noticeably higher (than the White Patch), and it does not appear nearly so white to the eye. That visible difference is dramatically obvious in Figure 5 (especially on the right sided image). Speer claims that the White Patch was caused by three overlapping layers of bone. Despite his unrelenting caricature to the contrary, I have always accepted three layers of bone at the overlap site, although I have never emphasized this because no one (before Speer) had offered such a novel explanation for the White Patch.

       Incidentally, the three layers of overlapping bone should be obvious to anyone after viewing the AP X-ray (an image that Speer overlooks). He also argues that, because the ARRB experts (p. 10 and also Chapter 19b, pp. 26-27) noticed such bone overlap, they therefore support his conclusion that the overlap explains the White Patch. But that is simply absurd. . . .

       Third, the White Patch is so dense that whatever physical object it represents must appear somewhere on the AP X-ray film. I made this argument from the very beginning, even at our first press conference in New York City (1993). That transcript is reproduced in [i]Assassination Science[/i] 1998 (p. 155) and warrants a quote here:

              On the frontal [AP] X-ray, such an extremely dense [physical] object should have been as visible as a tyrannosaurus rex in downtown Manhattan at noon. However, when I looked at the frontal X-ray, there was no such beast to be seen.

       No one has even tried to explain this paradox. Even worse, Speer seems oblivious to it. Let’s next focus on the OD issues for overlapping bone, a quantitative exercise that Speer totally neglects. For these JFK skull X-rays, here are the pertinent OD changes (∆ODs) across various layers of bone: one layer = 0.45; two layers = 0.90; three layers = 1.35. The difference for one layer is easily measured at fracture lines; amazingly enough, Speer believes that I ignore these fracture lines (p. 9). If an extra bone layer truly explained the White Patch, then sites just outside the White Patch should yield ODs that are higher by about 0.45 (one layer).

       But that is not the case—on the contrary, the ODs suggest a difference of more than just one layer of bone. Of special interest is the OD over the occiput, at the very back of the skull (very close to the White Patch), where the bone is viewed tangentially: the data there suggest a ∆OD (compared to the White Patch) of not just more than one layer, but actually about two bone layers (i.e., it is much less white). In other words, the White Patch is truly an anomaly (much too white and with ODs that are far too low). It cannot possibly arise simply from overlapping bone. On the other hand, of course, a deliberate superposition of this area in the dark room could easily explain this paradox. That the ODs of the White Patch and the petrous bone are not nearly so identical (to one another) on the left lateral X-ray should also raise some doubt that not all is well in OD land.

       Now recall that three layers of bone yield a ∆OD of 1.35. Since the measured OD (cited above) in the overlap area is already 1.33, the OD without the three layers of bone would be 1.35 + 1.33 = 2.68. The ODs in the maxillary sinuses (mostly air) are 2.89, so this value of 2.68 clearly suggests substantial missing brain in the overlap area. But the site in question (medial to the overlapping bone on the lateral X-ray) lies near the middle of the brain, where the autopsy photographs show no missing brain tissue!

Chapter 19a is a detailed history of my disagreements with Fetzer, and his supporters. The last 2/3 or so is about Mantik, who continues his attacks on me with the hope (I presume) I will remove this detailed account of his ever-changing claims and arguments. No further response is needed.
