Project Overview

The Rochester SPI identified violent retaliatory disputes as a primary driver of homicides, firearm assaults, firearm homicides, and shootings, with as many as 75 percent of homicides resulting from such disputes. The Rochester SPI implemented strategies similar to street outreach models to intervene in violent retaliatory disputes. To evaluate the effectiveness of the intervention, the researchers employed descriptive and correctional analysis, as well as logistics regression analysis.

Data Highlight

  • In 2012, shootings in Rochester were up 52.4 percent from 2011, the fourth-highest year for shootings over 10 years.
  • The outcome evaluation found no overall reduction in crime in Rochester as a result of the retaliatory violence intervention.
  • The evaluation served an important role in validating the assessment tool as a predictive device. Researchers found that for every one-point increase in a dispute’s assessment score, the odds of violence occurring in that dispute over time increase by 29 percent.
