Over the past decade, the Los Angeles Police Department has experimented with a unique model of community-oriented policing called the Community Safety Partnership (CSP). The program places a dedicated set of CSP officers in select housing developments and neighborhoods to engage with residents to better understand and ultimately address the root causes of crime. This study examined the first four waves of the program to assess whether, and the extent to which, the program reduced violent crime. Results reveal significant variation in program effects, with the first wave yielding crime reductions while subsequent waves experienced little to no change in violent crime. Supplemental analyses suggest that the null results for the final three waves of the program were not confounded by increases in crime reporting and reveal that crime reductions following the program’s first wave were not achieved through increases in traditional enforcement (e.g., arrests).
