People v. LaValle
People v. LaValle, 3 N.Y.3d 88 (2004), was a landmark decision by the New York Court of Appeals, the highest court in the U.S. state of New York, in which the court ruled that the state's death penalty statute was unconstitutional because of the statute's direction on how the jury was to be instructed in case of deadlock. New York has since been without the death penalty, as the law has not been amended.
Jack McCoy
Unlike his predecessor Ben Stone (Michael Moriarty), McCoy embraces the option of the death penalty, claiming it is a suitable punishment for particularly heinous crimes and a useful threat in plea bargaining. This often leads to heated arguments with his more liberal colleagues. In "Savages", when the death penalty has just been restored in New York following the election of Governor George Pataki, Kincaid asks McCoy about the probability of executing an innocent individual. McCoy responds that, with the lengthy prosecution process and opportunities for the defendant to appeal the verdict, the probability of wrongful execution is unlikely. Kincaid asks McCoy if he is able to accept the probability of "unlikely"; his hesitation indicates that he has never considered the possibility. In later seasons, his view towards the death penalty has apparently changed: in season 18's "Executioner", he is deeply troubled hearing of a gruesomely botched execution in South Carolina, and in season 20's "Four Cops Shot", he resists efforts by a U.S. attorney to prosecute a suspect in the murder of a police officer under a federal death penalty statute.
