Final answer:
The Supreme Court's decision in Miranda v. Arizona requires police to inform suspects of their Miranda rights, such as the right to remain silent and the right to an attorney, to protect their Fifth Amendment rights during interrogations.
Step-by-step explanation:
The issue of whether the police practice of interrogating individuals without notifying them of their right to counsel and their protection against self-incrimination violates the Fifth Amendment was notably addressed in the landmark case of Miranda v. Arizona. In that case, the Supreme Court established the requirement for police to inform suspects of their Miranda rights before any custodial interrogation. These rights include the right to remain silent, the right to an attorney, and the warning that anything said can and will be used against them in court. The ruling highlighted that without such notifications, any statement given by the suspect could be considered involuntary and, therefore, inadmissible in court. This set a precedent that ensures a suspect's Fifth Amendment rights are protected during the interrogation process.
