All legal technicalities aside, the Schiavo case boils down to one issue: an American court has ordered the death of an innocent (and defenseless) woman.
The American Declaration of Independence argues that God gives all people the rights to Life, Liberty, and the pursuit of Happiness. The American Constitution guarantees to all its citizens that neither Life, Liberty, nor property can be taken from them without due process.
If Mrs. Schiavo were a pedophile, or a murderer, or an abortionist, those calling for her death by dehydration and starvation would be protesting for her to have all legal options explored in preserving her life. A convict on Death Row would have all legal avenues exhausted and still many "kind-hearted" liberals would be arguing for a stay of execution.
This act of injustice is indefensible.
