Then I suggest you move to a different neighbourhood ... I dont' know ANYBODY who has been a victim of a home invasion. But how about instead of anecdotes (which are meaningless) we look at the facts. All crimes in South Africa has been steadily declining for decades, and murder has been declining faster than any other.
From your name I guess you, like me, are white. You have nothing to worry about. Of the murders that do happen - no race group is LESS likely to experience them than whites. Everyone else is at far greater risk than we are.
If you REALLY want to make the country safer, and you seriously believe guns will do that, donate your guns to poor black people. 

The ISS says whites make up a mere 1.8% of murder victims - and the vast majority of white murder victims are killed by members of their own family. Legal guns are more likely to be used to commit those murders than to prevent them.
