A diagnosis of PVS is in a sense hard to prove; easy to disprove. There are certain things a scan of a non-PVS person would often show, and a scan of a PVS person would never show. The presence of such things would contradict a finding of PVS, even though their absense would not necessarily imply one.
I don't know how long the original unedited videos were, but unless one were shooting hundreds of hours of video time, I don't think the chance reactions from a PVS patient would appear as purposeful as what's shown on the video.
Trying to remember back, isn't Greer Terri's surrogate?
Michael is Terri's guardian, though Greer also claims to represent her interest notwithstanding that the statutes explicitly forbid a judge from playing such a role excetpt in cases where the ward is a relative.
btw, your clever post on Portia made me drag out my Complete Works of Shakespeare. But I haven't gotten around to reading Merchants of Venice yet.
Well, Act IV Scene 1.
Maybe it's advocate, not surrogate. Near the beginning, there was a man who overlooked Terri's interests but Michael?? dismissed him?
Thanks for your help.
