First, cases involving gang-related homicide were selected,
since the majority of cases prosecuted by Operation Hardcore were gang
homicide cases. Second, individuals suspected by police as being
involved in these cases were identified by police records. Third, the
District Attorney's listings of individuals against whom criminal
charges had been accepted or rejected for prosecution were reviewed for
the names identified in the second step. Thus all names from step two
were classified as accepted, rejected, or not referred.
All cases referred by local police agencies for prosecution
to the Los Angeles District Attorney's office during 1976-1980.
