SAN FRANCISCO BAY GUARDIAN -- In 1971, a group of radicals broke into an FBI office in Media, Pennsylvania and stole a bunch of documents about J. Edgar Hoover’s surveillance program targeting dissidents and antiwar activists. Thanks to their criminal act, which they followed up by anonymously sending copies of the files to major media outlets, awareness of FBI spying under Cointelpro penetrated mainstream consciousness. More than 40 years later, the people behind that theft have unmasked themselves in a new book, “The Burglary: The Discovery of J. Edgar Hoover’s Secret FBI,” authored by Betty Medsger. The former Washington Post reporter convinced some of the burglars to come forward and tell their tale. Medsger previously served as chair of the Journalism Department at San Francisco State University.
