Which 1966 court case required suspects to be informed of their rights to satisfy the 5th Amendment's protection against self-incrimination?

• A. Miranda v. Arizona
• B. Plessy v. Ferguson
• C. Weeks v. United States
• D. Dickerson v. United States

Answer: (A)

Protecting the Fifth Amendment right against self-incrimination during police questioning is the focus here. In the 1966 ruling, the Supreme Court held that suspects must be informed of their rights before custodial interrogation. Those rights—usually called the Miranda rights—include the right to remain silent and the right to an attorney, with appointed counsel if you can't afford one. The idea is to prevent coercive questioning and ensure any statements or confessions are voluntary and informed. If these warnings aren’t given and a valid waiver isn’t obtained, the resulting statements are typically barred from use in court. While later cases reaffirmed the Miranda framework, this decision first established the requirement to notify suspects of their rights to satisfy the Fifth Amendment’s protection against self-incrimination. Other listed cases deal with different issues (one about racial segregation, another about the exclusionary rule, and another confirming Miranda rather than creating it).
