The U.S. Post Office ran a secret surveillance program that tracked civil rights leaders by opening their mail, photographing correspondence, and building dossiers on activists. From 1952 to 1973, the CIA examined 28 million letters under operation HTLINGUAL. Martin Luther King Jr., Malcolm X, and countless others had their private correspondence monitored. This is how everyday infrastructure became a weapon against the movement for equality.
