I seem to recall that the examiner was going to have an "observer" in on the autopsy, but at the last minute forbade any observation. It is not unusual to have bystanders and witnesses at an autopsy--and if an examiner wants to cover his rear for any reason, it's a real good idea for him to have witnesses. If I had been the examiner, I would have wanted a roomful for this contentious case.
What the ME has accomplished in this case by refusing to have an independent observer in the room, is to simply leave the case perpetually open. Nothing has been changed or accomplished by the autopsy. Even if he is correct in his findings, he is not credible because Pinellas County has been so rife with corruption even before the Schiavo case.
