THE WHOLE WORLD IS WATCHING MCCOY'S BIGGEST CASE -- INCLUDING SUPREME COURT -- IN SEASON FINALE -- The far-reaching probe into an old man's death precipitates Assistant D.A. McCoy's (Sam Waterston) most crucial case when he seeks to prosecute a high-level foreign dignitary for the torture-murder of a New York student 27 years ago, and the passionate McCoy is ready to argue the unprecedented case before the U.S. Supreme Court. He is aided by Detectives Briscoe (Jerry Orbach) and Green (Jesse L.
