Group Violence Intervention


The City of Jackson Group Violence Intervention (also called GVI) unites community leaders around a common goal: to stop gun violence and keep Jackson’s highest risk citizens alive and out of prison. 

GVI is a partnership among community leaders from law enforcement, government, education, civil service, health-care and faith-based agencies. Based on a proven model developed by David M. Kennedy, director of the National Network for Safe Communities at John Jay College of Criminal Justice, GVI advocates direct, sustained engagement with street groups that cause the majority of Jackson’s gun violence. The strategy empowers community members to set clear moral standards against violence in their communities and reclaim a voice in the way they want to live. It coordinates the efforts of local, state and federal law enforcement to focus crime prevention efforts on the groups most associated with gun violence. GVI also draws on the expertise of social service providers to offer group members a path away from violence.

Why use the term “Group” instead of “Gang”? The purpose of GVI is to reduce violence and to stop the killing. Research finds that most homicides and shootings are committed by members of highly active street groups—these groups are gangs, drug crews, and the like. All gangs are groups, but not all groups are gangs.

According to the National Network for Safe Communities, an exclusive focus on gangs, which is often understood to include notions like organization and leadership, will exclude a significant number of groups that contribute heavily to serious violence, such as loosely affiliated neighborhood drug crews.

The National Network’s experience shows that focusing on whether a particular city has gangs, or whether a particular group is a gang, is an unnecessary distraction that does not serve the goal of reducing violence because attention and resources are too narrowly directed. Many high-rate offenders associate in loosely affiliated groups—and these groups drive serious violence. Many, and often most, such groups will not fit the statutory definition of a gang. Nor will they meet even the common perception of what constitutes a gang. Such groups may or may not have a name, common symbols, signs or tags, an identifiable hierarchy or other shared identifiers.  


Why Group Violence Intervention? The City of Jackson is committed to using a proven approach to addressing group-related violence. This approach has been implemented in dozens of cities across the U.S. The group violence intervention approach has proven that violence can be dramatically reduced when community members and law enforcement join together to engage directly with these groups and clearly communicate:

  • A credible, moral message against violence
  • A credible law enforcement message about the consequences of further violence
  • A genuine offer of help for those who want it

 According to the National Network of Safe Communities, the key moment in the strategy is a “call-in”—a face-to-face meeting between GVI partners and members of groups.

At call-ins, the partners deliver key messages to group members:

  • That the violence is wrong and has to stop
  • That the community needs them alive and out of prison and with their loved ones
  • That help is available to all who accept it and that any future violence will be met with clear, predictable, and certain consequences
