Miranda is a legal principle that originated from the landmark U.S. Supreme Court case Miranda v. Arizona in 1966. It establishes the rights of individuals in police custody, ensuring protection against self-incrimination and guaranteeing the right to legal counsel.

The Miranda warning, also known as Miranda rights, is a statement read to suspects before any custodial interrogation takes place. It informs them of their rights to remain silent, has an attorney present during questioning, and warns that anything they say can be used against them in court.

The purpose of Miranda is to safeguard individuals’ Fifth Amendment rights and prevent coerced confessions. It has had a significant impact on criminal procedure in the United States.
