Edwards v. Arizona

Edwards (defendant), arrested for robbery, burglary, and murder, was read his Miranda rights and initially agreed to talk, but invoked his right to counsel partway through questioning without making incriminating statements, and was returned to his cell. The next day, officers came to question him again; Edwards told a guard he didn't want to talk to them, but the guard said he had to. The officers re-read his Miranda rights, and this time Edwards made incriminating statements. The trial court admitted the statements as voluntary, and Edwards was convicted; the state supreme court found Edwards had invoked both his right to silence and to counsel initially, but held he had effectively waived those rights the next day by voluntarily answering questions.
