The Evidence-Based Gun Violence Reduction and Prevention Act of 2025 seeks to implement a comprehensive strategy to combat gun violence in the District of Columbia through the establishment of a Group Violence Intervention Initiative. This initiative will focus on individuals and groups involved in gun violence, enhancing coordination among law enforcement and providing social services to those willing to change their behavior. A Governing Board, comprising key city officials, will oversee the initiative, while a Strategy and Implementation Team will manage daily operations. The bill also allows the Metropolitan Police Department to hire civilian personnel to investigate certain property crimes and cold cases, thereby increasing investigative capacity without displacing sworn officers.

In addition to these measures, the bill mandates the Sentencing Commission to produce a biannual report on repeat violent offenders and empowers the Mayor to address properties that pose a criminal blight. It also requires the Director of the Department of Healthcare Finance to amend the Medicaid state plan to include community violence prevention services for beneficiaries, allowing those exposed to community violence to access necessary support. The bill establishes criteria for certifying qualified violence prevention professionals, with the Department of Health and the Office of Gun Violence Prevention overseeing training and certification programs that include trauma-informed care and community violence prevention strategies.
