Project Coast was a biological weapons program that the South African government developed in the 1970's and 1980's. The leading scientist and administrator of Project Coast was a cardiologist called Wouter Basson This was a massive, ambitious weapons program that created both lethal and non-lethal weapons for strategic purposes, such as making black people sterile, and for tactical purposes such as assassinating political opponents.
Throughout Project Coast Wouter Basson was, allegedly, responsible for numerous murders by supplying biological weapons; in Operation Duel  Basson allegedly supplied lethal pills that killed 200 members of The South West Africa People's Organization.
Why wasn't Wouter Basson charged with crimes against humanity? From my research he is still free, is alive, and has never been found guilty of anything. The United Nations or The Hague have never attempted to charge Basson with crimes against humanity. Why?
