If you were to design a system to spot a certain kind of crime in real time, would you place it in zones historically more plagued by that kind of crime or in zones that experienced it scarcely? It's hard to buy into the rhetoric of "it's only fair if you monitor the crime equally" if you have already independently sampled it for decades and by now know the zones where it's much likely to happen.

Would you patrol a desert in the same way you patrol a busy road intersection if you're trying to prevent car accidents?
