Amnesty? Absolutely not.

Simply getting rid of Zuma is not going to magically fixed the problems. It's the same as taking out a mafia don. Another scoundrel steps in and takes his place. Why? Because, like the mafia don, there is a murky criminal empire running the back office in the shadows. And they are not likely to capitulate their ill gotten gains without a fight. There are lots of ANC characters (and others) that are in on the deal. They will all want to sustain the trappings of the patronage network.

Zuma is simply the enabler by virtue of the office he holds. Letting him off the hook just sets a precedent whereby it's okay to run a criminal empire. When you get caught you can just simply escape through the back door (amnesty, deals, golden handshakes etc.) and face no consequences. With such a scenario, the criminal justice system is rendered a toothless watchdog that does not even bark.
