At the end of 2010, the New York City Police Department had the most diverse force in its history, with a majority of rank-and-file police officers coming from minority communities, officials said...Christopher Dunn, associate legal director of the New York Civil Liberties Union, said diversity in the patrol-officer ranks is "certainly important, but that is not the end of the matter. Diversity in the command structure is just as important because commanders set department policy, supervise the work of the department, and in many ways are the face of the department."
