The the Mayor’s Office of Criminal Justice (MOCJ) facilitates cooperation and partnerships among the agencies and actors involved in crime-fighting and criminal justice in New York City. In doing so, MOCJ works to ensure the fair and efficient functioning of the criminal justice system in New York City. CJC serves as a liaison between the NYPD, the Departments of Corrections and Probation, the 5 District Attorney's Offices, and other agencies to help coordinate consistent citywide policy on criminal justice issues. MOCJ also advises the Mayor on criminal justice matters and is responsible for developing and implementing policies, legislation, and strategies in the fields of public safety and criminal justice. MOCJ has focused particularly in the past few years on special projects for the Mayor, including efforts to combat illegal gun trafficking, make better use of DNA evidence in investigations, and target quality of life offenders.
