And Richard Williams has died at the age of 58 from cancer after spending two decades in jail. He was a member of the United Freedom Front, a clandestine organization that was linked to about two dozen bombings in the late 1970s and early 1980s of government installations and corporations that backed the South African apartheid regime. He was arrested in 1984 and accused of a series of the bombings and the killing of a police officer. Advocates for political prisoners had long called for Williams’ release.
