Kansas City, Missouri
Reducing Violent Crime through Social Network Analysis-based Offender Targeting
The Kansas City, MO Smart Policing Initiative (KCMO SPI) aimed to reduce violent crime in the city, particularly murders and aggravated assaults with guns. The KCMO SPI began as a foot patrol project, but later shifted to an offender-based focused deterrence approach. The latter project became a citywide campaign called the KC No Violence Alliance (KC NoVA). Both projects focused on violent victimizations among high-risk individuals. KCMO SPI also created a process to sustain innovative strategies across the organization. Finally, the research partner used an interrupted time-series analysis to evaluate the impact of KC NoVA on violent crime. Results showed that foot patrol areas experienced a 26 percent reduction in aggravated assaults.
- From 2010 through 2013, Kansas City ranked among the worst of the 50 largest cities in the U.S. for homicide, averaging more than 100 per year.
- Results showed that foot patrol areas witnessed a 26-percent reduction in aggravated assaults and robberies during the 90-day project period.
- No reductions in crime were reported in control areas or in catchment areas surrounding the foot patrol areas.
- The focused deterrence strategy produced statistically significant decreases in homicides (40 percent) and gun-related aggravated assaults (19 percent).
