The Supreme Court held that a person in police custody cannot be questioned unless told that: 1) he or she has the right to remain silent, 2) he or she has the right to an attorney (at the government expense if the accused is unable to pay), and 3) anything the person says after stating that he or she understand these rights can be used as evidence of guild at trial. This warning will protect the accused from unknowingly giving up their Fifth Amendment protection against self-incrimination.
