What is considered to be the most difficult problem involving incriminatory statements made by juveniles during the course of police questioning?

The most difficult problem involving incriminatory statements made by juveniles during police questioning is determining the voluntariness and reliability of those statements. Juveniles often lack the maturity and understanding to fully comprehend their rights, leading to potential coercion or misinterpretation during interrogations. Additionally, the legal standards for admissibility can vary significantly, complicating the evaluation of such statements in court. This raises concerns about the adequacy of protections for juveniles in the justice system.
