Next special police squads were set up to monitor the turnstiles, arresting and charging the scofflaws. In the process of these arrests they found 1 in 7 had an outstanding warrant for a previous crime and 1 in 20 was carrying some sort of weapon. Eventually this bonanza began to reap rewards as criminals realized they had better pay their fares and leave their weapons at home. The same style of enforcement was then moved above ground and what would have been previously overlooked minor infractions such as public drunkenness, urination and littering were rigorously enforced. Before long the crime rate began to dramatically fall, just as it had in the subway. Tipping Points for violent crime proved to be minor, seemingly insignificant quality-of- life crimes. This is the Broken Window theory in action. Content adapted from Malcolm Gladwell’s Book “The Tipping Point”.
