An ongoing evaluation by John Jay College of Criminal Justice found one neighborhood experienced a 63% drop in monthly shooting victims from 2009 to 2016, based on New York Police Department data. New York spends approximately $40 million a year on Cure Violence programs. Slutkin estimates that big cities require about $15 million to $30 million to run an effective program, and small cities need $5 million to $10 million.
As Jeffrey Butts, director of the John Jay College of Criminal Justice research and evaluation center in New York City, noted four years ago, “the public health approach of [Cure Violence] CV currently merits the label ‘promising’ rather than ‘effective.’” “CV, however, offers something to communities that other well-known violence reduction models cannot,” he added. “It is potentially very cost-efficient, and it places less demand on the political and administrative resources of law enforcement and the larger criminal justice system. "
A John Jay College study compared a South Bronx neighborhood served by Cure Violence with a demographically similar neighborhood that did not have violence interrupters. But perhaps more promising than the decrease in shootings were the shifts in attitudes toward violence the John Jay survey found among young men in the neighborhood.
The John Jay College of Criminal Justice Research and Evaluation Center analyzed the New York City experience with the Cure Violence model in 2017, seven years after the strategy was adopted. It found reductions in gun injuries of 37–50 percent in the South Bronx and Brooklyn. The center also documented a 14 percent reduction in attitudes supporting violence, with no change in control populations. However, more research is needed.
