New Orleans news nonprofit The Lens releases “Neighborhoods Watched: The Rise of Urban Mass Surveillance,” a five-part series on the city’s rapidly growing surveillance apparatus. In obtaining and reviewing thousands of city documents, Michael Isaac Stein, Caroline Sinders, and Winnie Yoe demonstrate how a $40 million public safety plan created a “sprawling, decentralized and constantly changing patchwork of tools” maintained by various departments, agencies, private nonprofits, and law enforcement with little oversight.
