good fences make good neighbors

In countries with extremely high rates of violent crime and property theft, such as South Africa, a common means to prevent crime is for residential houses to be protected by perimeter defences such as brick walls, steel palisade fences, wooden palisade fences and electrified palisade fences (railings). The City of Johannesburg promotes the use of palisade fencing over opaque, usually brick, walls, as criminals cannot hide as easily behind the fence. Its manual on safety includes guidance, such as avoiding having vegetation alongside the fence, as this allows criminals to make an unseen breach.[7]
