“Are there connections between these three shifts - a decrease in crime, a decrease in the correctional population, and a sharp increase in controversial police practices? What factors contributed to these shifts? What about the costs of these shifts? Have they been evaluated and weighed against the benefits? In this report, leading criminologists James Austin and Michael Jacobson take an empirical look at these powerful social changes and any interconnections. Examining data from 1985 to 2009, they conclude that New York City’s “broken windows” policy did something unexpected: it reduced the entire correctional population of the state. As the NYPD focused on low-level arrests, it devoted fewer resources to felony arrests. At the same time, a lowered crime rate - as an additional factor - meant that fewer people were committing felonies. This combination led to fewer felony arrests and therefore fewer people entering the correctional system. Other policies - like programs that stopped punishing people with prison if not necessary - also contributed to this population drop” (p. 3). Sections of this report following an executive summary are: decline in New York prison population-drop in admissions and increase in statewide length of stay; decline in New York parole, probation, and jail populations; delayed effect on state corrections budget; accompanying drop in New York City’s crime rate and shift in arrest policy; and conclusion.
