nor shall any State deprive any person of life, (except Terri Schiavo) liberty,(except Terri Schiavo) or property(except Terri Schiavo), without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
The case was in court for years. Terri had plenty of due process.
She was allowed to expire and now truly at peace.
Since she was not in need of anything except artificial means of nutrition, I think there was arguably a moral fault with removing those means. It wouldn't matter if removing such nutrition been her written wish or not, the moral dilemma would still exist. The courts (and there were multiple involved) determined her wishes under the law despite interference, protestations, propaganda, etc. If anything, she got more due process than nearly any one in similar circumstance.
The husband did not murder. He may have killed, but it wasn't murder. The moral of the story is get yourself a living will if you want to avoid the potential becoming another case like Mrs. Schiavo.
