Which case established the requirement to inform suspects of rights prior to police questioning?

• A. Gideon v. Wainwright
• B. In Re Gault
• C. Brown v. Board of Education
• D. Miranda v. Arizona

Answer: (D)

The main idea here is protecting a person’s Fifth Amendment rights during police questioning. Miranda v. Arizona established that suspects must be informed of their rights before any custodial interrogation and must knowingly waive those rights to have their statements used in court. The warnings cover things like the right to remain silent and that anything said can be used against you, the right to consult with an attorney, and the right to have an attorney appointed if you cannot afford one. If the police don’t provide these warnings, the statements obtained are typically excluded from evidence, because the person wasn’t making a truly voluntary and informed choice to speak.

The other cases involve different protections: Gideon v. Wainwright guarantees the right to counsel in criminal cases; In Re Gault extends due process rights to juveniles in delinquency proceedings; Brown v. Board of Education bans racial segregation in public schools. The specific requirement to inform suspects before questioning is the Miranda decision.
