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) is designed to reduce street group-involved homicide and gun violence. Pioneered by National Network Director David Kennedy and colleagues as “Operation Ceasefire” in Boston during the 1990s, it has been implemented widely nationally, including currently in the very challenging cities of Chicago, New Orleans, Oakland, and Baltimore, and has acquired a strong formal evaluation record, as presented in the gold-standard Campbell Collaboration Systematic Review.
GVI has repeatedly demonstrated that violence can be dramatically reduced when a partnership of community members, law enforcement, and social service providers directly engages with the small and active number of people involved in street groups and clearly communicates a credible moral message against violence, prior notice about the consequences of further violence, and a genuine offer of help for those who want it. A central method of communication is the call-in, a face-to-face meeting between group members and the strategy’s partners.
The aim of the GVI strategy is to reduce peer dynamics in the group that promote violence by creating collective accountability, to foster internal social pressure that deters violence, to establish clear community standards against violence, to offer group members an “honorable exit” from committing acts of violence, and to provide a supported path for those who want to change.
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.

National Network Director David Kennedy recently paid a visit to partner city South Bend, Indiana as they continue to implement their group violence intervention.
"Crime is down in Gary, a news release issued by city officials announced. Mayor Karen Freeman-Wilson praised Gary police officers "for their untiring service to the Gary community," adding that "nearly all police and fire personnel received pay increases in 2015 and 2016."
"The YMCA of Metro Chicago project connects kids like Courtney-Clarks, who live in high-violence neighborhoods, with veterans who have served in Iraq or Afghanistan and who might understand what they're going through...The Urban Warriors program is built on the idea that these kids are experiencing trauma and need to process it, and that witnessing or experiencing violence can affect how they behave at home, react at school, or lead them to commit violence themselves."
"Federal law enforcement agencies are working more closely with big-city police departments in Connecticut to fight violent crime, the state’s top U.S. prosecutor said in an interview. Cooperation has been particularly effective in New Haven, where the police department has begun regularly sharing intelligence, U.S. Attorney Deirdre Daly said. Representatives from Daly’s office, federal and state agencies, New Haven police and other local departments huddle together daily in meetings that began this month."
"Officials from the Suffolk County Police Department, Suffolk County Probation, FBI and ATF today announced the creation of a firearm suppression team aimed at removing illegal guns from Suffolk County streets at a press conference in Hauppauge. F.A.S.T, Firearm Suppression Team, will target individuals who pose the most significant threat to the safety of Suffolk residents and will aim to remove illegal firearms from the county’s streets. F.A.S.T. will focus its attention on communities that are most affected by firearm-related crimes."
This article profiles "Kids Off the Block," a community initiative in Chicago that "provides a safe space for youth who experience gun violence as part of everyday life." The program, coupled with the Chicago Violence Reduction Strategy, is producing important results for young people in these Chicago neighborhoods.
Police Commissioner Bill Bratton discusses the important steps the NYPD is taking to combat crime in New York City as well as the results that were produced in 2015. In addition to generally positive crime trends, the NYPD has worked, with promising results, to decrease enforcement encounters including a 96% decline in stop and frisks since 2011. Commissioner Bratton writes that "the NYPD and New York City’s many diverse communities are supposed to be allies, but the way we have done business in the past has often kept us from finding common ground. We will find the common ground we seek on local ground."
"The Stockton Police Department released statistics Wednesday showing that the city’s crime rate hit a 15-year low in 2015, a sign of progress in a community that has been besieged by violence in recent years. Jones said the statistics validate policies put in place to reduce violent crime in Stockton, including the Marshall Plan, Operation Ceasefire and the Neighborhood Blitz Team."
Rosilyn Temple leads the Kansas City chapter of Mothers in Charge, a community support group for people who have lost children to homicide. After Ms. Temple's son was tragically murdered in 2011, she began working with Mothers in Charge to help mothers who were suffering under the same circumstances as her. She has been extremely active and important member of the Kansas City Community and the city's No Violence Alliance. Joe Ledford
New Haven rounded out 2015 with a significant drop in the number of "shots fired" incidents it reported. The total number of homicides stayed relatively constant but some New Haven leaders are crediting Project Longevity with aiding this impressive decline in shootings.
