• Individual Gun Violence Intervention

    The Individual Gun Violence Intervention (IGVI) is designed to reduce gun violence by individual offenders.

About the Strategy
Tools & Guides

The Individual Gun Violence Intervention (IGVI) shares the National Network’s guiding principles in its approach to reducing gun violence by individual offenders. Pioneered as Project Safe Neighborhoods (PSN) in Chicago, the IGVI strategy brings parolees with histories of violence and/or gun offending into a call-in; informs them of the legal risks of, especially, the federal felon-in-possession gun laws to which they are now subject; conveys clear antiviolence messages from community members and ex-offenders, and spells out social service opportunities. Careful evaluation has found substantial reductions in gun violence as a result. The approach is now being replicated in several sites across New York State and elsewhere.

The results of Chicago PSN have been dramatic, as have those of other initiatives based on the IGVI approach. Multiple evaluations have shown reductions in gun violence in treated areas compared with untreated areas. Additionally, ex-offenders who have been engaged by Chicago PSN call-ins consistently show a greater likelihood of staying alive and out of prison.
