Between April 28 and May 7, 1971, over 12,000 people were arrested during a series of anti-war protests in Washington, D.C. – it became known as the largest mass arrest in U.S. history. Along with many volunteer attorneys from the ACLU and other organizations, over forty attorneys from DC’s Public Defender Service played a critical role in providing emergency representation for the detainees, many of whom had never before been arrested. This Special Report of the Board of Trustees of the PDSDC, chaired by Samuel Dash, details the activities of the PDS staff during the Mayday protests. The digitized report is now available in Digital Georgetown — permalink: https://repository.library.georgetown.edu/handle/10822/1041061
