in homicides or assaults. (C) Strategies, including group violence interventions (referred to in this section as GVI ), which are a form of problem-oriented policing that provides targeted social services and support to individuals at highest risk for involvement in community violence, and a process for community members to voice a clear demand for the violence to stop. This approach coordinates law enforcement, service providers, and community engagement efforts to reduce violence among a small, identifiable segment of the population that is responsible for the vast majority of gun violence in most cities. In one evaluation of the GVI program in Boston, researchers found a 63-percent reduction in youth homicides and a 25-percent decline in monthly gun assaults across the city. Other studies have found that GVI programs were associated with homicide reductions of up to 60 percent. (10) These strategies are often most effective when local officials and dedicated staff work to coordinate stakeholders, relevant public agencies, and service providers. Mayors in cities like Los Angeles and New York have established city departments that are primarily dedicated to violence prevention, and their offices have played a critical role in ensuring cross-agency collaboration and information-sharing. (11) These strategies are also most effective when they receive consistent funding. For example, large cuts in funding for violence prevention programs in Chicago in 2008, 2012, and 2015 through 2016 corresponded with large spikes in homicides in those years. Similarly, the city of Stockton, California, saw an increase in homicides after discontinuing funding for its highly successful GVI program. When Stockton’s funding was restored, homicides decreased. (12) A national strategy for reducing gun violence must include substantial and targeted Federal funding to expand and replicate the most effective strategies in communities most impacted by violence. (13) At present, however, these strategies are implemented in only a handful
