Through Jan. 15, 2019, the National Building Museum and the Historical Society of Washington, DC, present “Community Policing in the Nation’s Capital: The Pilot District Project, 1968-1973.” Employing original documents, maps, posters and other materials, the exhibition tells the story of the District’s innovative experiment in community policing. It also commemorates the 50th anniversary of 1968 riots. The Pilot District Project launched in the summer of 1968 in what is now most of Ward 1 had broad goals for police reform and citizen participation. Although deemed a failure at the time, the it saw several important innovations during its five-year run including: 24-hour police stations, citizen ride-alongs and police sensitivity training. National Building Museum is at 401 F St. NW. nbm.org.
