Dirty Tricks

South African President F.W. de Klerk replaced his military intelligence chief after an investigative commission charged that officials drafted a plan to hire a convicted murderer last year and have him lure African National Congress members into dealings with drug dealers, prostitutes and homosexuals. The plan for dirty tricks, apparently never carried out, was uncovered by the Goldstone commission on violence, which is looking into abuses by South African security forces. In 1990 De Klerk declared that he was putting an end to all such covert operations.
