Project Overview

The Los Angeles SPI sought to reduce gun-related violence in specific neighborhoods through application of the Problem-Oriented Policing (POP) SARA (Scanning, Analysis, Response, and Assessment) problem-solving model. The team implemented Los Angeles’ Strategic Extraction and Restoration Program (Operation LASER) and conducted location-based strategies in five hot spot areas for violent crime, as well as offender-based strategies through the creation of a Crime Intelligence Detail (CID). The CID’s primarily mission was to produce police intelligence bulletins on individuals with high likelihood of involvement in chronic crime. These bulletins assisted officers, detectives, and other personnel in identifying crime trends, addressing chronic offenders, and solving ongoing investigations. Results showed a statistically significant decrease in Part I violent crimes, homicide, and robbery in the Newton Division (one of the Los Angeles Police Department’s [LAPD] most chronic high violent crime areas). 

Methods and Findings

Research Design

Interrupted time-series analysis, which assesses whether the interventions in target areas had an effect on crime while controlling for previous trends.

Findings

22.6% reduction in homicides per month in the target division.

5.2% reduction in gun crimes per month in each reporting district of the target division.
