In the 1990s, the New York City Police Department expanded its focus on reducing behaviors that detract from the overall quality of life (QOL) in the city. Many have credited this effort for the decline in the city's overall crime rate. They often cite the fixing broken windows argument, which maintains that reducing disorder sets off a chain of events leading to less crime. However, systematic research has not yet documented this chain of events. Looks at one of the first linkages, whether QOL policing sends a message to offenders not to engage in disorderly behaviors in public locales. The project interviewed 539 New York City arrestees in 1999. Almost all of them were aware that police were targeting various disorderly behaviors. Among those that engaged in disorderly behaviors, about half reported that they had stopped or cut back in the past six months. They reported a police presence was the most important factor behind their behavioral changes. These findings support the idea that QOL policing has a deterrent effect.
