Effects of Impaired Verbal Abilities on Miranda Comprehension and Reasoning: "Do You Understand Your Rights?"

Description: In Miranda v. Arizona (1966), the Supreme Court of the United States required that custodial arrestees be informed of their constitutional and continuous rights to silence and to legal counsel. Moreover, the ruling mandated that waivers be considered valid only if they were made knowingly, intelligently, and voluntarily. However, in the decades that followed, evidence from both caselaw and empirical scholarship clarified that, for many vulnerable populations, these rights are in jeopardy. Among… more
