I was particularly surprised to read that he was instrumental in defining determination of death from a heart that permanently stopped beating to the cessation of brain waves.
I also read that his definition of PVS is substantially different from the state of Florida's stricter difinition and that the court transcript shows that Judge Greer used Dr. Cranford's definition in assessing Terri.
Terri's case is simply a setup. Schiavo wants rid of her, Felos wants to further euthanasia and Greer has an interest in this somehow too.
