To be sure, Bratton has some bragging rights. The crime rate plunged in the cities where he served as chief. The problem with taking too much credit for this is that during this same time, crime fell across the country. Bratton suggests in the book, co-written by Peter Knobler, that the national trend showed that his “methods were adopted by more and more police departments.” For most of his career, Bratton has been the stern face of “broken windows” policing. The theory, popularized in an Atlantic magazine article by criminologists James Q. Wilson and George L. Kelling, is that fear of crime is driven more by signs of disorder than by actual violence — which, even during peak periods of crime, only a small percentage of people experience. In this view, “order-maintenance” policing, including strict enforcement of quality-of-life crimes such as public drinking, prevents more serious offenses.
