Richard Santoro (Gary Basaraba) was the station's desk sergeant, a police veteran who had seen it all and was the voice of reason in the station house, keeping things calm. Santoro later stuck up for Donovan when he came out as an informant for Internal Affairs Bureau to save Santoro from a corrupt IAB officer who was trying to ruin Santoro's reputation. Ray MacElwaine (John Finn) was a 50-year-old veteran police officer who transferred to the 74th Precinct late in the series and soon proved himself to everyone that despite his age, he could still "walk the beat" and take down criminals. MacElwaine also stuck up for Donovan after finding out Donovan's work with IAB. In the series final episode, MacElwaine decided to retire from the police force, and Santoro was promoted to Lieutenant. So, Captain Jonas threw a double-party for the entire police station in celebrating Santoro's promotion and MacElwaine's retirement. In his speech, MacElwaine changes his mind and decides not to retire, to great celebration.
