Eddie Lee Mays
Mays would become the last person to be executed by "Old Sparky", New York State's electric chair at Sing Sing prison. The State Electrician was Dow Hover. The electric chair had been the sole method of execution in the State since 1890 (hanging had been abolished in 1888). In 1965, the State of New York repealed the death penalty, except for cases involving the murder of a police officer. Although the legislature never fully repealed the death penalty statute, and the state even expanded it in 1995, there were no further executions because of rulings by the U.S. Supreme Court in 1972 and the New York Court of Appeals in 2004.
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.
