The FBI's Criminal Justice Information Services (CJIS) Division provides critical support to law enforcement agencies across the United States. It manages a variety of databases that include criminal records, fingerprint identification, and information on missing persons. This helps police and other agencies solve crimes and maintain public safety. CJIS also oversees the National Crime Information Center (NCIC), which allows law enforcement to access real-time data on criminal activity. Additionally, it offers training and resources to help agencies effectively use these systems, ensuring that they can respond quickly and accurately to criminal incidents.
