Content:  Stone's departure from Law & Order stemmed from actor Michael Moriarty's dispute with the network and U.S. Attorney General Janet Reno, who in 1993 began promoting legislation to limit portrayals of violence on television. Moriarty, who was outspoken against Reno and what he felt was government censorship, was scheduled to appear on NBC shows Today and Now with Tom Brokaw and Katie Couric, but both ended up canceled. Moriarty had already taped his segment for Now; for his Today show appearance, during which he was scheduled to debate Senator Kent Conrad, he was replaced by FCC chairman Reed Hundt. Both appearances were scheduled to air on January 26, 1994. Moriarty submitted his resignation to producer series creator Dick Wolf on January 25, 1994, and his departure was written into the series.
Title: Benjamin Stone (Law &amp; Order)
Content:  Stone became Executive Assistant DA in 1985 after convicting con artist and murderer Philip Swann (Željko Ivanek), who years later enters a civil suit against Stone when the validity of the conviction is called into question. Swann is ultimately found guilty, however, and sent back to prison. Stone's assistants have been Paul Robinette (Richard Brooks) and Claire Kincaid (Jill Hennessy). A strict, unyielding boss, Stone can be very difficult to work with; in the pilot episode, Sergeant Max Greevey (George Dzundza) and Detective Mike Logan (Chris Noth) intimate that Stone "eats ADAs for lunch." Nevertheless, Stone is usually rather soft-spoken, and is fond of using harmless words like "sir" to convey his contempt for the people he prosecutes. Stone makes his last appearance in the show in the episode "Old Friends," the final episode of season four. The episode portrays a racketeering case in which the main witness Ann Madsen (Allison Janney), whose testimony Stone had secured by threatening to send her to prison, is murdered by the Russian Mafia. He feels responsible for her death and resigns from the DA's office. He is succeeded by Jack McCoy (Sam Waterston) as Executive ADA.

Stone is divorced and has a son, Peter Stone (Philip Winchester), who was the Deputy Chief of the Special Prosecutions Bureau in Chicago and was the Chief ADA of the Sex Crimes Bureau in New York, and a daughter, Pamela (Amy Korb). Stone's prosecutorial methods are portrayed as being grounded in moral principles stemming from his Catholic faith. He is shown to be anti-abortion and opposed to the death penalty. He also is a strong advocate of social justice, having marched in the civil rights movement. It is implied that Stone, like actor Moriarty, is a Dartmouth College alumnus, with references to "fraternity row" and New Hampshire.
