One recent development in the battle against gun violence has shown promise, however. That involves the use of technology to streamline and support police enforce-ment and investigatory efforts against criminals who carry guns. This report examines one of these promising technology-based applications: the Crime Gun Intelligence Center (CGIC) model. CGICs are an interagency collaboration among local police departments, the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), and other partners such as state and local prosecutors, to identify perpetrators of gun crime for immediate inves-tigation, apprehension, and prosecution. CGICs combine state-of-the-art analytical technology, data processing systems, and good old-fashioned detective work to help police agencies more quickly analyze ballistic evidence, establish connections among seemingly unrelated crimes, and build criminal cases targeting both gun traffickers and trigger-pullers.
