Final answer:
The police practice of interrogating individuals without notifying them of their right to counsel and their protection against self-incrimination may potentially violate the Fifth Amendment.
Step-by-step explanation:
The police practice of interrogating individuals without notifying them of their right to counsel and their protection against self-incrimination may potentially violate the Fifth Amendment of the United States Constitution. The landmark case of Miranda v. Arizona in 1966 established the requirement for police to advise criminal suspects of their rights, including the right to remain silent, the right to consult with a lawyer, and the right to have one appointed if unable to afford one. If the suspect explicitly and unambiguously requests to have an attorney present, the police interrogation must stop.
