Former South African president PW Botha dead at 90 [audio 4min]

PW Botha, who served as South Africa's last hard-line white president, has died at 90. Nicknamed "The Big Crocodile" for his belligerence and temper, Botha was the face of racist South Africa at the height of its anti-apartheid struggle. Known for his finger-wagging speeches in which he refused to accept the notion of black rule in South Africa, Botha's era passed him by when apartheid fell. He never accepted responsibility for some of the heinous crimes that transpired during his regime. Report by Charlayne Hunter-Gault.
