It's funny, but in South Africa crime and especially theft is very common, and at the same time, personal property sometimes find their way back to you.

This especially tends to happen if for example you were robbed and your wallet was left behind or let's say the police were harassing you and threw your driver's license over a fence or something (true story).

I think the reason for this is that the serial criminals are really <1% of the population and probably >50% are really just normal and usually decent people.
