How can I protect myself in South Africa?

The best you can do to protect yourself is to stay out of trouble. You do that best by using common sense and exercising basic safety precautions.

Avoid isolated areas, especially at night. Don’t go out alone if you don’t have to. When you are alone or in pairs, avoid groups of young men, especially in the dark, just change the side of the road as subtly as you can. If you walk alone in the dark think of your destination and getting there quickly, preferably in a car.

If ever anybody tries to mug you, let them! Give them everything and try to stay calm. Credit cards, ID and phones can be replaced, your life cannot.
