In the landmark Miranda case, the Supreme Court ruled that the Constitution’s guarantee against self-incrimination required that police warn criminal suspects about their right to remain silent and to have a lawyer present when they are taken into custody for questioning.
Now the court has ruled in J. D. B. v. North Carolina that police need to consider a suspect’s age when deciding whether they must give him Miranda warnings.
Under earlier rulings, the court said that whether a suspect was “in custody” for Miranda purposes depended on the circumstances of the interrogation and whether a reasonable person would have felt free to leave.
In its new decision, the court concludes that age matters because a teenager is likely to think he is not free to leave an interrogation even if a reasonable adult would think otherwise.
