National Crime Gun Intelligence Center InitiativeCGICs are an interagency collaboration focused on the immediate collection, management, and analysis of crime gun evidence, such as shell casings, in real time, in an effort to identify shooters, disrupt criminal activity, and to prevent future violence. CGICs rely on an ongoing collaboration between the ATF, local police department, the local crime laboratory, probation and parole, local police gang units, prosecuting attorneys, U.S. Attorney’s Office, crime analysts, community groups, and academic organizations.
