The Group Violence Intervention (GVI) reduces violent crime when community members join together with law enforcement and social service providers to focus an antiviolence message on highly active street groups.
The Group Violence Intervention (GVI) has shown repeatedly that a city can dramatically reduce homicide and gun violence when community members and law enforcement join together to directly engage with these groups and clearly communicate 1) a credible, moral message against violence; 2) a credible law enforcement message about the consequences of further violence; and 3) a genuine offer of help for those who want it.
Pioneered by National Network Director David Kennedy and colleagues as "Operation Ceasefire" in Boston during the 1990s, the intervention was responsible for a 63 percent reduction in youth homicide that came to be known as “The Boston Miracle.” The strategy requires that people from disparate backgrounds, often with competing priorities, work together in unusual ways and focus on a single goal: reducing serious violence in their community.
A real working partnership among stakeholders within law enforcement, community members and social services is the strategy’s most important element and also its greatest challenge. The explicit aim is to reduce pro-violence peer dynamics within gangs by creating collective accountability, fostering internal dynamics that deter violence, establishing community norms and standards against violence, and giving gang members who want it an “honorable exit” from the street life.
The National Network produced Group Violence Intervention: An Implementation Guide, published by COPS Office in 2013, to provide a practical tool for stakeholders seeking to implement GVI in their jurisdiction.
A comprehensive guide to the National Network's Group Violence Intervention strategy. This guide covers all relevant steps to the strategy from initial planning and problem analysis to enforcement actions and call-in implementation, and further considers issues of maintenance, integrity, sustainability and accountability to offer interested parties a step-by-step guide to successfully implementing GVI in any jurisdiction.
This guide provides practical information about "custom notifications," an independent element of GVI that enables quick, tactical, direct communication to particular group members. This publication presents the custom notifications process, explains its value within the broader strategy, details its use by several national practitioners, and encourages further development.
This guide begins with a brief description of the shooting scorecard concept and its links to problem analysis and performance measurement systems in police departments. It then presents the key steps in the process and associated data quality issues and then details the use of shooting scorecards by the Boston Police Department as an example of the practical applications of this approach.
A complete guide for law enforcement, community, and social services partners already engaged in implementing the Group Violence Intervention to design, prepare, and execute their first and subsequent call-ins.
For the Group Violence Intervention to achieve its desired outcomes, stakeholders must be authentic and their messages credible. For law enforcement this means making good on the promise of swift and meaningful consequences for a group or gang as a whole when a prohibited violent act (usually shooting or killing) is committed by one of its members. This document captures examples of successful and creative law enforcement responses to group violence as carried out by police departments and their partner agencies in key National Network jurisdictions.
This paper briefly reviews the research on the crime control effectiveness of "pulling levers" focused deterrence programs. Focused deterrence strategies honor core deterrence ideas, such as increasing risks faced by offenders, while finding new and creative ways of deploying traditional and non-traditional law enforcement tools to do so, such as communicating incentives and disincentives directly to targeted offenders.
This report is a meta-analysis that evaluates impact on homicide and violence in a variety of cities that have implemented our Group Violence Intervention or the Drug Market Intervention.
This is a May 16, 2013 "call-in" meeting of the Philadelphia Focused Deterrence initiative, at which Philadelphia community members, law enforcement, and social service providers join together and use the National Network for Safe Communities' method of communicating directly with active gang and street group members.
This is a September 23, 2014 "call-in" meeting of the Baton Rouge Area Violence Elimination (BRAVE) initiative, at which Baton Rouge community members, law enforcement, and social service providers join together and use the National Network for Safe Communities' method of communicating directly with active gang and street group members.
In this brief, K. Tate Chambers outlines a step-by-step application of the New Orleans Strategy to combat violent street crews and how it was employed in Don't Shoot Peoria's focused deterrence crime prevention plan. This article outlines the 14 steps used by Don't Shoot Peoria to implement the focused deterrence strategy and also explains some of the practical applications of these steps.
The Institute of the Study & Practice of Nonviolence in Providence is a national pioneer in training and employing professional street outreach workers to address and prevent violence. It has also forged a highly effective partnership with the Providence Police Department that the National Network for Safe Communities believes can serve as a model for other jurisdictions seeking to utilize street outreach workers as part of implementing the Group Violence Intervention. In this webinar, the Institute’s Executive Director Teny Gross and Streetworker Program Manager Ajay Benton discuss the following key issues: Principles and Practice of Nonviolence; Training; Hiring & Firing; Partnering With Police, Schools, and Hospitals; Selecting Target Clients; Managing Risks; Managing Public Relations; Measuring Success.

This webinar focuses on innovative techniques for communicating key messages to offenders, potential offenders and affected communities as part of the National Network's group violence reduction and drug market strategies. Key issues include: Best practices in the "classic" call-in format; Voluntary call-ins for gang members; Home visits with impact players; Custom legal assessments; Prison call-ins; The use of "influentials" in both strategies; Emphasizing legitimacy in the call-in; Use of social network analysis.
Social network analysis is an integral part of Chicago's Violence Reduction Strategy (VRS). It is used to expand and improve the police department's intelligence on gangs, groups and local gang factions; to identify the most socially connected group and gang members to take the VRS anti-violence message back to their associates; and to assess the impact of law enforcement efforts on groups or gangs. This document outlines three examples of social network analysis as a tool to narrowly and effectively focus law enforcement resources on group violence.
Social network analysis— the scientific tool behind social media like Facebook and Twitter—is used widely in the private sector to understand markets and organizations and in the health sector to understand the spread of disease. It can be used just as effectively to devise new ways to reduce violent crime. Leadership Group jurisdictions Chicago and Cincinnati have been at the forefront of applying social network analysis in crime prevention. In this webinar, Andrew Papachristos, Ph.D., a national expert and the research partner of the Chicago Police Department, and Captain Daniel Gerard of the Cincinnati Police Department will demonstrate how social network analysis is applied in the context of the Group Violence Intervention. Key issues addressed include: Mapping of group, gang and faction structures and relationships; designing surgically precise enforcement actions; expanding knowledge of group membership using commonly available administrative data; identifying the most influential group members for taking antiviolence messages back to affiliates.

A report about the groundbreaking home/street visits approach developed by the Cincinnati Initiative to Reduce Violence (CIRV) to keep its anti-violence message "fresh" in between its formal court house call-ins. The CIRV team identifies key impact players within groups active in crime hot-spots, meets with them face-to-face at their homes or in the streets, and delivers the message in a way that has led to substantial reductions in shootings around the city.
This brief explores the role and purpose of demonstration, and subsequent, group enforcement actions ("crackdowns") associated with the law enforcement component of the Group Violence Intervention, including talking points for presenting these actions within actual call-ins/notification meetings with group and gang members.
This PowerPoint presentation summarizes findings from an evaluation of the impact of Project Safe Neighborhood (PSN) initiatives on neighborhood level crime rates in Chicago. Several PSN interventions were found to be associated with greater declines of homicide in the treatment neighborhoods compared to the control neighborhoods. Out of four interventions analyzed, the largest effect was associated with the offender notifications that stress individual deterrence, normative change in offender behavior, and increasing views on legitimacy and procedural justice.
This PowerPoint presentation, by Robert A.J. Lang, Assistant U.S. Attorney for the Middle District of North Carolina, and Jodi A. Ramirez, Law Enforcement Coordinator/Program Manager of Project Safe Cabarrus, sets out how to create the partnerships and agency structures necessary to successfully implement and sustain the group violence strategy. It includes guidelines on how best to overcome common institutional barriers as well as best practices for sustaining the initiative.
This PowerPoint presentation, by CIRV Executive Director Greg Baker, provides an outline of the structure, processes and outcomes of the initiative, aimed at reducing gun violence and homicides in Cincinnati.
The document provides a description of the Project Manager position in this initiative. The Project Manager is responsible for coordinating community-wide resources, agencies, and committees as part of the federally funded Project Safe Neighborhood (PSN) initiative. PSN is based in part on the National Network's group violence strategy.
This PowerPoint presentation by the High Point Police Department includes an outline of the theory underlying the group violence strategy, a step-by-step implementation guide, a link analysis of the groups engaged in violent crime in High Point, and details of the department's organizational realignment to more effectively support its mission of crime reduction.

An effort is being made in Peoria to help reduce repeat offenses. Those who've had a run-in with the law can reach out for help, thanks to the Don't Shoot initiative.
Nine men with ties to local gangs were told to put the guns down, or risk going to jail — and to take the message back to their “group.”
Nine people, all with ties to gangs, were told to put the guns down and take that message back to their "group." That message was given at Monday night's Don't Shoot Call-In.
A South Bend man who took part in the South Bend Group Violence Intervention (SBGVI) strategy now faces 63 months in prison on gun charges.
United States Attorney for the Northern District of Indiana, David Capp, announced that James Dean Garcia, Jr, 33, of South Bend, Indiana, was sentenced today, for being a felon in possession of a firearm. Garcia was sentenced to 63 months imprisonment and two years of supervised release.
Over the last nine months, our country has lurched from crisis to crisis concerning police/community relations and police use of force: from Ferguson, Mo., to New York City, to Cleveland, Ohio, to North Charleston, S.C., to Tulsa, Okla., and now Baltimore. Each time, we hear pledges of police department reform. This raises a question: What does a good police department look like?
Last month, a team including some of New York City's top law enforcement officials met with a group of men who are—in the estimation of the police, at any rate—among the likeliest in Brooklyn to kill or die by gunfire.
"People in these neighborhoods don't like chaos and destruction," said Kennedy, who has been advising Baltimore on its Operation Ceasefire strategy. "It's being driven by a small, number of people."
While the city has seen a recent uptick in homicides and shootings, the numbers are actually down in Brooklyn. Police officials give some credit to the decline in Brooklyn to a program called Operation Ceasefire.
“Operation Ceasefire is working,” said NYPD spokesman Stephen Davis. The program, which started in December, reaches out to gangbangers and potential recruits, offers them social services, and tries to persuade them to refrain from violence that can get them killed.
