David Aceveda, played by Benito Martinez, is a character on FX's television crime drama The Shield. Originally, he was the captain of "the Barn", a police precinct in the fictional Farmington district of Los Angeles, California. However, in Season Three, he was elected to the Los Angeles city council and effectively relinquished command in the first episode of Season 4. Though he is no longer captain, his responsibilities as the city council representative of the Farmington District often keep him in the forefront of the show. According to show creator Shawn Ryan's commentary on the Season 1 DVD, the Aceveda character is heavily influenced by current Los Angeles mayor Antonio Villaraigosa.
