Arthur Caplan, the bioethicist from University of Pennsylvania Hospital has been involved in experimenting on patients without their informed consent. He was sued for it. Now he advocates killing patients without their consent. There are some sick twisted freaks out there.
Your son was fortunate to have such good parents. It's hard to think of the abuse and torture he may have suffered otherwise. Most parents, even good parents, would never suspect their child's doctor of subjecting them to abuse. It just flies in the face of everything we always knew to be true. Doctors are compassionate people, who care about their patients. Some still are, but you can no longer count on getting one who is. And a doctor who is backed up by an ethics department is less likely to have ethics.
What a coincidence that A. Caplan is from Pennsylvania where the schiavos are from.
