Howard "Bunny" Colvin is a fictional character on the HBO drama The Wire, played by actor Robert Wisdom. Colvin is a wise and able police major in the Baltimore's Western District, alienated by the careerism and bureaucracy rampant in the Baltimore Police Department and the detrimental social effects of the War on Drugs. Close to retirement, he secretly breaks chain of command and puts his resources into "Hamsterdam," three zones within his district where drug dealers are pressured to non-violently congregate in exchange for informal legal sanction.
