Zuma was a member of the ANC, so of course the ANC Women's Leaque would want him released. Pistorius isn't a member of the ANC.

Also, they're upset that he was granted bail, as they feel he's a flight risk, this is related to the English guy who had his wife killed while in SA on honeymoon and then was granted bail and fled back to the UK where they won't extradite him.

I'm not entirely sure Pistorius isn't a flight risk.

What false assumptions & mistakes have the police made? The only issue with the police that I'm aware of is that the lead detective had to be taken off the case because he's in some legal trouble of his own that had nothing to do with the Pistorius case.
