fourth season. Two other actors also joined the starring cast, having previously portrayed their corrupt characters as guest stars—Michael Kostroff as defense attorney Maurice Levy and Isiah Whitlock Jr. as State Senator Clay Davis. Crew member Clark Johnson appeared in front of the camera for the first time in the series to play Augustus Haynes, the principled editor of the city desk of The Baltimore Sun. He is joined in the newsroom by two other new stars; Michelle Paress and Tom McCarthy play young reporters Alma Gutierrez and Scott Templeton. Episodes Season 1 The first season introduces two major groups of characters: the Baltimore Police Department and a drug dealing organization run by the Barksdale family. The season follows the police investigation of the latter over its 13 episodes. The investigation is triggered when, following the acquittal of D'Angelo Barksdale for murder after a key witness changes her story, Detective Jimmy McNulty meets privately with Judge Daniel Phelan. McNulty tells Phelan that the witness has probably been intimidated by members of a drug trafficking empire run by D'Angelo's uncle, Avon Barksdale, having recognized several faces at the trial, most notably Avon's second-in-command, Stringer Bell. He also tells Phelan that no one is investigating Barksdale's criminal activity, which includes a significant portion of the city's drug trade and several unsolved homicides. Phelan reacts to McNulty's report by complaining to senior Police Department figures, embarrassing them into creating a detail dedicated to investigating Barksdale. However, owing to the department's dysfunction, the investigation is intended as a façade to appease the judge. An intradepartmental struggle between the more motivated officers on the detail and their superiors spans the whole season, with interference by the higher-ups often threatening to ruin the investigation. The detail's commander, Cedric Daniels, acts as mediator between the two opposing groups of police. Meanwhile, the organized and cautious Barksdale gang is explored through characters at various levels within it. The organization is continually antagonized by a stick-up crew led by Omar Little, and the feud leads to several deaths. Throughout, D'Angelo struggles with his conscience over his life of crime and the people it affects. The police have little success with street-level arrests or with securing informants beyond Bubbles, a well known West Side drug addict. Eventually the investigation takes the direction of electronic surveillance, with wiretaps and pager clones to infiltrate the security measures taken by the Barksdale organization.
