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.
When was Thogmartin corrupt? He is highly respected as a Medical Examiner.
The "outside expert" that the Schindlers wanted in the room was Cyril Wecht, a notorious grandstander and media hog, who is, as we speak, being investigated by the federal government.
