Breakthrough on broken windows

I remain unconvinced that “disorder” is a cause of crime. It seems to me that the increased police presence and attention to particular high crime areas are probably the main factors in the reduction in calls to the police. If the criminals see an increased police presence in an area I am betting that they change areas rather than permanently stopping the commission of crime. I am all for cleaning up a neighborhood, but I am not expecting that alone to reduce illegal activity.
