Lets ask an obvious question. Why this appeasement of Zuma by way of the amnesty proposal? There may well be a broader front in the ANC behind this than we are aware..concerned to save the carcass. After all, did Zuma not say  recently that he would not go down alone? Add his statement to all the slug holes the ANC has sustained recently and this gambit reveals desperation to keep life in the soon to be corpse.
