Two things to note:
Firstly, the rider remained calm and was lucky not to be shot. Many have commented at the video that a gun wouldn't have helped in this situation. See my second point for my answer.
Secondly, the stupid woodheads didn't even see he had a camera strapped to his head, and as a result, have been captured. I'm betting next time they'll shoot whoever they hold up, so if you have a gun, use it first!
This video has over 1.3 million views already. Hopefully a lot of people are seeing the reality of South Africa now.
