South Africa has one of the highest crime rates in the world.
It used to be ruled by a small group of white people who made black people live by strict rules, even though the huge majority of the country is black.
This system, called apartheid, ended in 1994.
But there was loads of violence and crime because of the unfair system.
People hoped there'd be less crime after apartheid ended, but it hasn't really happened.
Many violent crimes have actually gone up.
