Another part of their law, unless it's changed since last I heard: If you shoot in SD, miss and hit an innocent person, it is the same as if you shot the innocent person intentionally, the equivalent of aggravated assault or murder.
A great story about SD in S. Africa is "Shooting Back" by Charl Van Wyck, regarding the St. James Church Massacre in 1993. Two terrorists and a getaway driver attacked a church service with automatic rifles and grenades. Their mission, found out after they were arrested, was to kill at least 500 people. Van Wyck was a visiting missionary and concealed carrier. He chased the terrorists off with just a Rossi 5-shot snubby, keeping the toll down to 11 dead and 58 wounded.
Van Wyck also had another encounter with terrorists sometime later, driving through a small town with a friend. The three bad guys stopped their car, searched them and robbed them. But then it started to seem like the bad guys were going to eliminate witnesses. When the terrorists got a momentary distraction, Van Wyck drew a G26 from an ankle holster, which the search had missed. He opened fire, which allowed Van Wyck and his friend to get back in the car and speed off.
He comes to the states occasionally. He has been a guest speaker for the VCDL. There is a video of one of his talks on YouTube somewhere. It's really good.
