MT: And you get this bit of wisdom from where, exactly?
Umm, how about the sources I listed in that same reply, for starters? How about the above-mentioned wound ballistics tests? How about the fact that nowhere in published forensic cases will you find a case where an FMJ bullet deposited a single fragment, much less two or more, at or near the entry point on a skull?
And I notice none of you are tackling the stunning absence of the low fragment trail on the autopsy skull x-rays and the equally stunning absence of any mention of the high fragment trail in the autopsy report, not to mention the autopsy doctors' 1966 five-hour review of the autopsy materials and their failure to note the high fragment trail and their assertion that the materials they reviewed confirmed the autopsy report.
Of your sources, Drs Smith and Fillinger only said that they had not seen it, not that it had never happened in all medical forensic history. Dr Green only said that "it would generally not occur," which implies that it does. Dr Berg was the only one to deliver an unequivocal "No", referencing DiMaio's
[Gunshot Wounds. But DiMaio has this to say about the subject:
"In gunshot wounds of the skull, a large fragment of lead may be deposited between the scalp and the outer table of the skull at the entrance site. This piece of lead is sheared off the bullet as it enters. With lead .32 revolver bullets and less commonly with .38 bullets, this fragment often has a “C” or comma-shaped configuration (Figure 11.7). Rarely,
the tip of the jacket of a full metal jacketed bullet is so deposited." (DiMaio,
Gunshot Wounds: Practical Aspects of Firearms, Ballistics, and Forensic Techniques, 2nd Ed. Ch 11)
That is, Berg's source directly contradicts Berg's position. And says that FMJ bullets do indeed shear off bits on the outer table.
So, I'm still wondering where you got the idea that "no FMJ bullet in the known history of forensic science has deposited a fragment, much less multiple fragments, at/near the entry point when striking a skull."
