For some reason, the State did not follow through, after appearing to put in so much work with Spitz re: the skull issue
JA painstakingly drew Spitz's attention to the position of the hair in order to force acknowledgement (on Spitz's part) that this, the position of the hair, illustrated that the skull had not remained permanently on the left side, as Spitz insisted.
The follow-through required JA to then assertively challenge Spitz's contention that the residue within a portion of the skull was brain-tissue remnant. Had JA continued this line of logic, it would have done a great deal to demolish Spitz's claim that opening of the skull of skeletonized remains was absolutely necessary, indeed, 'protocol', and in doing so, Spitz's repeated criticism of Dr. G
However, JA backed-off at the critical juncture and this was regarded by many commentators as JA's unwillingness to subject the eminent Spitz to any further public humiliation ... a sentiment which was generally applauded and subsequently seemingly rewarded via Spitz's reported admiration for JA
Imo, JA needed to hammer home -- for the sake of the jury -- the points he'd seemingly been at such pains to establish throughout his lengthy and often confusing exchange with Spitz. But JA didn't follow through and via his numerous emphatic claims that Dr. G should have opened the skull, Spitz doubtless impressed upon the jury that Dr. G had failed to follow 'protocol' and had thus failed to gather vital information
