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.
