Gang databases are computerized lists maintained by law enforcement agencies that record information on individuals suspected of being gang members or associates. These databases are designed to help police manage, investigate, and track gang-related activity, and can include details such as names, photographs, known associates, and alleged affiliations with specific groups.
Authorities claim that gang databases are a useful tool for combating gang violence and solving crimes, as they allow for the centralization and sharing of intelligence among different law enforcement agencies. For example, the widely used CalGang database in California and the NYPD’s Criminal Group Database in New York City are prominent examples of such systems.
However, the criteria for inclusion are often vague and secretive, sometimes requiring only minimal evidence such as associating with known members, wearing certain clothing, or being present in specific areas. People—often youth of color—can be added without their knowledge, criminal conviction, or an opportunity to contest their inclusion. This lack of transparency and due process, combined with racial disparities in who is targeted, raises substantial civil rights concerns.
