Sunninghill Crime

It doesn't seem to be all that sunny when it comes to crime in Sunninghill, Johannesburg. I drive through the medium density residential suburb of Sunninghill about twice a week on my way to work. And for the past few weeks this pile of rubble that sat alongside of the road intrigued me. Yes intrigued is what I am, because I noticed that whoever was in charge of security in Sunninghill pointed their security cameras to watch that no one takes the small pile of rubble. Aaah crime must have been rampant in Sunninghill for them to put up cameras to watch dirt. Bonus, the camera must work because the rubble is still there for over two weeks since I first noticed it. My question is, who is watching the watchers?
