NYPD Blue

Diane continues to wrestle with her mother's uncertain legal future and takes out her anger on ADA Leo Cohen, who is reluctantly prosecuting her mother in the shooting of her dad, and later on the troubled son of a rich alcoholic who may have shot and killed his wife. Her mom's attorney works out a deal for her mom to get probation, but Diane doesn't handle the son well at all and it costs her a chance to solve the case. Bobby later grabs Cohen by the neck and threatens him if he smirks about Bobby and Diane's relationship again. In legal news, the honest working son of a Mafia boss is shot to death. Some other robbery-homicides and a revelation about the other son being gay lead to his arrest, not that he's sorry or cares about the people he's murdered and the lives he's destroyed.
