In People v. Cockrell (1965) 63 Cal.2d 659, the court found Griffin error in the admission of evidence that the defendant, after arrest and while in custody at the police station, remained silent when a police officer confronted him with an accusatory statement by a codefendant and asked what he had to say about "that." "Even though it does not appear that Mr. Cockrell made any statement indicating that he was invoking his privilege against self-incrimination, he had a right to remain silent and an inference adverse to him may not be drawn from his silence." ( Id., at p. 670.)
