There is something perversely delightful about the state Supreme Court’s decision in the case of State v. Lishan Wang. Call it the revenge of informed consent in legal ethics.

The Lishan Wang case is unusual. The defendant is a physician accused of murder. He is alleged to have killed a colleague whom he believes to have cost him a job at a Brooklyn hospital. The state says Wang opened fire on the decedent in Branford, killing him.
