Rational robbery

...criminals implicitly weigh up the costs and benefits of crime. A high probability and cost of detection reduces crime, all other things equal; a low likelihood of detection, a low likely cost (such as a negligible prison sentence or a caution, as has too often been the case in the past) and a larger payoff (flat screen TVs or expensive trainers) raises it. Many of those storming shops made that very calculation this week, albeit implicitly and in some cases incorrectly.
