Unfortunately James Q. Wilson this morning in the Wall Street Journal is subscription only, but I’d grab a copy if you can. Some of it:

That moral imperative should be that medical care cannot be withheld from a person who is not brain dead and who is not at risk for dying from an untreatable disease in the near future. To do otherwise makes us recall Nazi Germany where retarded people and those with serious disabilities were “euthanized” (that is, killed). We hear around the country echoes of this view in the demands that doctors be allowed to participate, as they do in Oregon, in physician-assisted suicide, whereby doctors can end the life of patients who request death and have less than six months to live. This policy endorses the right of a person to end his or her life with medical help. It is justified by the alleged success of this policy in the Netherlands.
But it has not been a success in the Netherlands. In that country there have been well over 1,000 doctor-induced deaths among patients who had not requested death, and in a large fraction of those cases the patients were sufficiently competent to have made the request had they wished.
Keeping people alive is the goal of medicine. We can only modify that policy in the case of patients for whom death is imminent and where all competent family members believe that nothing can be gained by extending life for a few more days. This is clearly not the case with Terri Schiavo. Indeed, her death by starvation may take weeks. Meanwhile, her parents are pleading for her life….

But that excerpt alone doesn’t do it justice, unfortunately.
