The trial of a South African doctor accused of multiple murders under the Apartheid regime. Wouter Basson, nicknamed 'Dr Death' by the country’s media, was alleged to have run a secret chemical and biological weapons project in the 1980s to eliminate perceived enemies of the government. But after the country’s longest and most expensive trial and despite evidence from 150 witnesses, in 2002 a judge found him not guilty on all 46 charges. Bob Howard talks to Dr Marjorie Jobson, the national director of Khulumani, a group which campaigns for justice on behalf of the victims of apartheid.
