S9, E21: As Detectives Briscoe (Jerry Orbach) and Curtis (Benjamin Bratt) investigate the death of an audio installation salesman, their search introduces them to a web of players who are all linked to the murderer, and consequently, the mafia. When Assistant DA's McCoy (Sam Waterston) and Carmichael (Angie Harmon) go to work, they face a remorseless suspect who has plenty of 'friends' who will give anything to keep him out of prison. To build a strong case against the suspect, McCoy and Carmichael face the challenge of convincing witnesses to testify and ensuring their safety. Later, District Attorney Schiff (Steven Hill) is forced to step in to adjust McCoy's ideas of proper punishment for the accused. S. Epatha Merkeson also stars.
