There's a principle in law called "the best evidence rule".
Now, it's not about EEGs vrs CAT/PET scans, it's about documents, but there is a similar point to be made in this instance.
The point is this: would you be willing to make a life-or-death decision on less-than-the-best evidence, when the best evidence is available?
Of course not.
Given the range of affidavits and observations from caregivers, I simply refuse to believe the purported EEG results, and would demand corroberation using "the best evidence".
Since you now say you refuse to believe the results I assume the actual reported results contradict your assertion completely.
And another question, since I have an expert like you at my disposal. What test is used to determine brain death in other patients on life support? Is it the EEG that you now disparage in the Schiavo case?
