Why are professors at Harvard, Duke, and Middlebury teaching courses on David Simon's The Wire?

Slate Magazine: "Among the police officers and drug dealers and stickup men and politicians and dockworkers and human smugglers and teachers and students and junkies and lawyers and journalists who populate the late, great HBO series The Wire, there is one academic. His name is David Parenti and he teaches social work at the University of Maryland, Baltimore. He is not a major character, but he appears throughout the show's fourth season—an earnest, well-meaning man defined in part by his naïveté about the inner-city kids whose lives he wants to improve. As for Johns Hopkins, Baltimore's best-known university, it only comes up as a place where the show's police officers can get cushy campus security jobs after they retire. Academia, in other words, is not a culture that the show's creators, David Simon and Ed Burns, betray much interest in exploring."
