Police officials across the United States are increasingly relying on place-based approaches for crime prevention. In this article, we examine the Safer Cities Initiative, a widely publicized place-based policing intervention implemented in Los Angeles's “Skid Row” that focused on crime and disorder associated with homeless encampments. Crime reduction was the goal. The police division in which the program was undertaken provides 8 years of time-series data serving as the observations for the treatment condition. Four adjacent police divisions in which the program was not undertaken provide 8 years of time-series data serving as the observations for the comparison condition. The data are analyzed using a generalized additive model. On balance, we find that this place-based intervention is associated with meaningful reductions in violent, property, and nuisance street crimes. There is no evidence of crime displacement.
