Final answer:
The police practice of interrogating individuals without informing them of their right to counsel and protection against self-incrimination can 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 can violate the Fifth Amendment. The Fifth Amendment protects individuals from self-incrimination, meaning they have the right to remain silent and not answer questions that could potentially be used against them in a court of law. The Supreme Court has established that suspects must be informed of their rights, known as the Miranda warning, before any custodial interrogation.
