Sadly, very sadly, South Africa has become a trigger happy society. Every second person owns a gun and discharging a firearm is extremely common place.
Before we left in 2000, we would be woken at night by the sound of gunfire, sit bolt upright in bed, scared, and phone the local police station (around the corner from our home) and the on duty policeman would say "It's nothing, it's just people (in the nearby informal settlement) testing their home made weapons." We often heard the gun shots night after night. In time, we would still stir, but turn over and go back to sleep. Unbelievable when I think of it now.
