Numerous states require parental notification, consent, or involvement in police interrogations of juvenile suspects, presumably to advocate for youths’ rights and protect against police coercion. Such laws presuppose that parents possess the knowledge, capacity, and inclination to serve this protective function, yet little is known about parents’ understanding of interrogation rights and procedures or their decision-making in juvenile interrogations. In this talk, Todd Warner will share the results of a study collected from a geographically diverse sample of over 500 parents. Specifically, this study tested parents’ knowledge about youths' interrogation rights, their awareness of police interrogation practices, and their advisements to youth regarding Miranda waiver across different custodial contexts to begin to assess whether parents themselves can advise youth competently.
