Problem-oriented policing, deterrence, and youth violence: An evaluation of Boston's operation ceasefire

Operation Ceasefire is a problem-oriented policing intervention aimed at re ducing youth homicide and youth firearms violence in Boston. It represented an innovative partnership between researchers and practitioners to assess the city's youth homicide problem and implement an intervention designed to have a substantial near-term impact on the problem. Operation Ceasefire wa s based on the "pulling levers" deterrence strategy that focused criminal j ustice attention on a small number of chronically offending gang-involved y outh responsible for much of Boston's youth homicide problem. Our impact ev aluation suggests that the Ceasefire intervention was associated with signi ficant reductions in youth homicide victimization, shots-fired calls for se rvice, and gun assault incidents in Boston. A comparative analysis of youth homicide trends in Boston relative to youth homicide trends in other major U.S. and New England cities also supports a unique program effect associat ed with the Ceasefire intervention.
