Imo, Dr. G used a different technique to determine the same thing that Dr. S feels should be determined through opening the skull. New school vs. old school. I think Dr. S either believes that old school is the only reliable and thorough way, or part of his objective on the stand was to give examples of how Dr. G's work was "shoddy" and he had no protocols to support his contention, so he used the fact that she didn't do it like he would have (and an unfounded insinuation that evidence photos were improperly posed) to try and discredit the ME's rulings. That was his job today. I found him completely lacking credibility, but that's just my personal judgment and we all see things differently.
I have zero doubt in my mind that Mr. Ashton will call Dr. G as a rebuttal witness to explain why she did not open the skull. If she was able to get the same thorough results without having to do so (by using a different technique) she will tell us. If she used a less thorough method and just did not think it was necessary or proper to examine the skull to the fullest extent, she will explain why. At that time, I think we and the jury will have enough information to determine if something was done "shoddily" or not. No medical protocols have been produced in this thread (that I saw) to indicate that a vital step was skipped in the autopsy of skeletal remains.
Until then, we were discussing who we found more believable. For me, Dr. G was much more credible and backed up her science and her opinions. She came across as a little uncomfortable and defensive to me, but I understand because I know the history of the defense's tactics with her and she probably has a healthy ego too. I think the jury may not have felt as warmly towards her as most of us do, but I don't believe they would have had any reason to doubt her credibility or passion. She was not evasive; solid.
Dr. S, on the other hand, could not back up anything and could not remember or did not bother to learn much about the critical circumstances leading up to the death. If it turns out that it might have been somewhat better to open up the skull (other than for Dr. S's reason of it it being a "national case"), we can give Dr. S that point and then judge for ourselves whether it would have made any difference whatsoever in how Dr. G ruled the death or how little Caylee died.
