Summary View help for Summary
The International Association of Chiefs of Police (IACP), collaborating with research partners, conducted a 48-month, two-phase research initiative to enhance their understanding of how firearms move from legal purchase to involvement with a crime. Phase 1 used trace data from Chicago, New Orleans, and Prince Georges County, MD to establish the path of firearms from purchase to usage in a crime. Interviews of the first legal purchaser and incarcerated inmates who committed a crime of violence in New Orleans and Prince Georges County were conducted to seek an understanding of how firearms enter the unregulated market. Phase 2 examined the use of the Group Violence Reduction Strategy (GVRS) in New Orleans as a strategy to reduce gang and gun-related homicides. Overall violence patterns in New Orleans were examined from 2010-2016.

The International Association of Chiefs of Police commissioned two research teams under award funds for this study, resulting in two NIJ final reports.
Study Purpose View help for Study Purpose
To understand regulated and unregulated gun markets, how guns move from the former to the latter, and how law enforcement can limit access to guns by those who will use them to commit a crime.
Study Design View help for Study Design
This study consisted of two phases:
Phase 1 was an analysis of trace data from three jurisdictions (Chicago, New Orleans, Prince Georges County, MD) to establish the path from legal purchase of a gun to use in a crime. Interviews were also conducted of inmates then incarcerated for violent crimes involving a firearm to hypothesize how one would obtain a firearm; and of first legal purchasers who were not offenders.
Phase 2 was an examination of the impact of the Group Violence Reduction Strategy in New Orleans, a deterrence framework to reduce gang and gun-related homicides, which was implemented in 2012. Violence patterns from 2010-2016 were looked at to encompass the the beginning and end of GVRS.
