In Los Angeles, mass stops of young African American men and boys resulted in the creation of a database containing the names, addresses, and other biographical information of the overwhelming majority of young black men in the entire city. The LAPD justified its database as a tool for tracking gang or “gang-related” activity. However, the criterion for inclusion in the database is notoriously vague and discriminatory. Having a relative or friend in a gang and wearing baggy jeans is enough to put youth on what the ACLU calls a Black List.
