Technological advances have enabled criminal justice organizations to collect and share offender data. Accompanying these advances are concerns about how various segments of the criminal justice system utilize these data. Specifically, scholars have expressed concerns about the legal consequences of being included in gang databases. This study explored the use of gang affiliation indicators on prosecutorial outcomes by using a sample of 5,111 urban juvenile cases. Using three binary measures of gang affiliation, multinomial logistic regression analysis suggested indicators of gang affiliation influenced prosecutorial outcomes (dismissal, pre-adjudication informal supervision, deferred prosecution, or petition), but in an unanticipated manner. Confirmed gang affiliates, instead of suspected or non-gang affiliates, were significantly more likely to experience pre-adjudication informal supervision over other forms of case outcomes: case dismissal, deferred prosecution, or court petition. Policy implications focus on the inter-connectedness of the criminal justice system.
