John Doman was born in Philadelphia, Pennsylvania on January 9, 1945. He was featured in a cameo role in the Clint Eastwood film, Mystic River, as well as a guest appearance in an episode of Star Trek: Deep Space Nine. He is best known for his role as Baltimore Deputy Police Commissioner William Rawl in HBO's critically acclaimed police drama, The Wire.
William A. Rawl is the Deputy Commissioner for Operations at the Baltimore Police Department. He is one of the most ruthless and demanding officers on the team, with a particular distaste for insubordination. Because of this, he has an ever-growing resentment towards Jimmy McNulty, who goes around the chain of command to get things done. Since majority of Baltimore's population is African-American, he cannot achieve commissioner status, and his current position may be the highest he can possibly have.
