Which Supreme Court case established the requirement to inform suspects of their rights before questioning?

• A. Mapp v. Ohio
• B. Miranda v. Arizona
• C. Gideon v. Wainwright
• D. Brown v. Board of Education

Answer: (B)

This is about the rights a person must be told before police questioning. The Supreme Court decision that established this requirement is the one that created the now-familiar Miranda warnings: when someone is in custody and being interrogated, police must inform them of their right to remain silent and their right to an attorney, and any statements made can be used in court. If the person cannot afford an attorney, one must be provided. This ruling protects against self-incrimination and ensures any waiver of rights is voluntary and informed. Other well-known cases deal with different protections: one established that illegally obtained evidence cannot be used in court (the exclusionary rule at the state level); another guarantees an attorney for defendants who cannot afford one; and a third declares that racial segregation in public schools is unconstitutional. None of those establish the requirement to inform suspects of their rights before questioning.
