FW freed a man from prison in 1990 that used to plant bombs in his spare time. At one instance killing many innocent woman and children in restaurants. 

In the years preceeding the 94 elections, tribal violence, especially in KZN, was a massive problem. FW's government could not prevent all of that.... admittingly so. 

Go watch the movie "Tainted Heros". I think it might be on YouTube.
