South Africa appears more violent than Brazil. I don’t know about this statistically but I observed a whole different level of property protection. The Bible School where we had the AVLN conference was surrounded by two fences, about half a meter apart. The outside fence is chain-link with razor-wire at the top. The inside fence is 20 rows of electric wire that go right down to the ground.
I went for a walk down the road a couple of miles. Properties are all highly protected with double fences or high walls. Some also have a Neighborhood Watch type of service claiming a 5-minute armed-guard response to breakins. I asked a local about this and he said that the countryside used to be where wealthier people lived, but now they prefer gated communities because these acreages are too dangerous.
