This is one of the only studies in the country to document the sustained impact of a community violence intervention (CVI) program on citywide firearm violence over more than 10 years.

According to lead author Alice Bruno, a doctoral student in epidemiology at UC Berkeley's School of Public Health, "We leveraged data from dozens of comparable cities across the United States to estimate what firearm violence would have looked like in Richmond without the ONS Peacemaker Fellowship. We found that the Fellowship contributed to long-term reductions in violence, and that the declines only grew as the program operated." Other UC Berkeley co-authors include Dr. Mahasin Mujahid, chair of the Division of Epidemiology; Dr.

Sean Darling-Hammond; and Dr. Sam Vaughn, director of ONS, said, "The statistics back up what we have seen in the streets: fewer shootings, fewer deaths and a healthier community overall." Homicide rates are down across the country; the FBI recently released data showing murder rates are down a record 18.1% nationally. However, Richmond has consistently outperformed national declines for more than a decade, suggesting the results are due to the city's innovative street outreach interventions and mentorship of active firearm offenders.

The program, called Operation Peacemaker Fellowship, was instituted in 2010. The Fellowship uses a public health approach to preventing gun violence. According to James Houston, program manager of the ONS, who oversees the day-to-day implementation of the Peacemaker Fellowship, including managing 14 street outreach workers who currently serve 123 participants, "The credit goes to the young people making better decisions and the team that gives them support, mentorship and encouragement every day to make a change." According to Shasa Curl, Richmond city manager, Richmond had more than 300 police officers FTE in 2014 and 180 in 2020 but was down to 121 active sworn officers by 2024.

Yet during this time, the ONS, through continued city support and grants, was able to expand its staff and increase the number of fellows and participants. Even during the COVID-19 period, the study shows Richmond did not have as significant a spike in firearm violence as most cities across the Bay Area and nationally. According to the ONS, the health impacts are lives saved, safer streets and community members with a renewed positive outlook on life.

One former Peacemaker Fellowship participant said, "Before the ONS came to me, I didn't care if I survived past 19, as long as I had a name in the streets. After my experience with the ONS, with my mentor coming at me every day, I got support for my stress, got a job, am paying my bills and have a kid now. I'm no longer terrorizing my community." The paper notes the cascading health benefits for entire communities when gun violence reductions are sustained, such as in Richmond.
