Don't know how much documented info Baden had, do know he was faxed information after his appearance on Thurs eve with Greta where he cast a dubious prognosis for Terri and seemed to back Shiavo and his attn along with the other panel members.
Greta had him on the next night, Friday, and it was evident that Dr Baden had changed his mind about terri's situation, syaing he had received and reviewed medical scans relating to terri (and I am sure the additional opinions reflecting those scans) and pondering outloud if an investigation into foul play had occurred.
I think I recall Baden even stating that Terri could be a candidate for rehab as she wasn't pvs. A 180 from the night before wherein he stated that she couldn't hear. Terri's family talks to her every day. Her brother told her daily during her starvation-dehydration period they were going to get her out of there. That's reported in the media somewhere. Terri's a strong girl.
Personally, I'm against starvation-dehydration as an option for end of life protocol. It is not painless as alleged. Too many Americans are being starved-dehydrated to death and this all started when our attentions were elsewhere.
