I like to think in some ways you don't have to work in a police department and you don't have to sell drugs [to relate to that] if you watch the show carefully. I take great satisfaction in the fact that some white guy in Timonium can watch the show and watch what D'Angelo goes through and think, "That's my fucking job. The bosses are assholes, and good help is hard to find. Middle management sucks, brother. I'm with you." And on the other hand, somebody who is actually in D'Angelo's situation down on North Carey Street selling drugs right now might watch the show and see McNulty's world, and up until that precise moment, his complete attitude toward the police was, "Fuck the police, I hate them, they're bastards, I hope they all die." He's completely alienated from law enforcement, as anybody would be on the other side of a war. And he watches what McNulty goes through, the aggravation of trying to just do his job, and thinks, "God, that's my job. The bosses are assholes, and good help is hard to find."
