Miranda rights are a set of legal rights that must be read to a person when they are taken into police custody and before being interrogated. These rights inform the individual that they have the right to remain silent and the right to an attorney. The purpose is to protect the person's Fifth Amendment right against self-incrimination. The requirement to read Miranda rights comes from the 1966 U.S. Supreme Court case Miranda v. Arizona. If law enforcement fails to provide these warnings, any statements made by the suspect during interrogation may be inadmissible in court.
