Which decision established the requirement to inform suspects of rights before custodial interrogation?

• A. Gideon v. Wainwright
• B. Miranda v. Arizona
• C. Terry v. Ohio
• D. Mapp v. Ohio

Answer: (B)

The main concept being tested is the rule that suspects must be informed of their rights before custodial interrogation. This requirement comes from Miranda v. Arizona, which holds that before police question a person in custody, they must read a set of warnings: the right to remain silent, that anything said can be used against them, the right to consult with an attorney and to have one present during questioning, and that if they cannot afford an attorney, one will be appointed. These warnings ensure the suspect’s understanding of their rights and that any waiver of those rights is voluntary, helping to protect the Fifth Amendment privilege against self-incrimination. If the warnings are given properly and a voluntary waiver is made, interrogation may continue; if not, the statements obtained may be excluded from evidence in court. Other landmark cases address different protections: Gideon v. Wainwright guarantees the right to counsel at trial, not during custodial interrogation; Terry v. Ohio deals with stop-and-frisk procedures based on reasonable suspicion; Mapp v. Ohio extends the exclusionary rule to state courts.
