Although I believe that Judge Greer should be subject to a civil rights suit, under 42 U.S.C. Section 1983, I doubt that it will happen. He will not be criminally prosecuted as the courts will find that he merely applied the law.
I believe he is a murderer in the moral or biblical sense, not the legal sense, as his actions have been affirmed by the appellate courts.
I believe that M.S., Judge Greer and the others who murdered Terri Schiavo will be judged and punished for their actions, but not in a court of law.
By what authority can a judge forbid a person from receiving oral hydration?
If Greer's order had ordered a discontinuance of a feeding tube, and allowed Michael to allow or disallow oral hydration as he saw fit, that might be allowable legally. But as it's written, Greer's order would require that Michael bodily stop Terri if she tried to get up and give herself a drink. How can that possibly be legitimate?
