New York City’s crime rate has remained at relatively low levels even as the size of the police force has fluctuated. This reflects a basic reality that decades of evidence have made clear: police and incarceration have diminishing returns as tools of public safety. There is only so much that police arriving after a crime has occurred can do, and there is a hard limit to how much public safety can be improved by incarcerating low-level offenders. Both strategies carry enormous social and fiscal costs, often without delivering lasting reductions in harm.
Truly improving public safety means investing in the strategies that are actually proven to reduce dangerous situations before they escalate—approaches that address instability, untreated illness, and systemic failure rather than managing the consequences after the fact.
