As with most serious subjects, there's a joke going around that these signs were put up to show newbie criminals where to start!

So I'm curious; How many people have something similar in their countries, or is this unique to South Africa? Any comments?

This is why more people need to carry guns.

That is where the guns used for robberies probably come from.

at camping grounds there are signs telling you to cover all valuables, but no signs telling you where crime occurs, otehr than the signs in christchurch that say where the crime prevention camera area starts

My sister went to Oklahoma, and she took a picture of a sign that said "Warning! Hitchichers may be escaped inmates."
