William O. Douglas,
Griffin v. California — Opinion of the Court
“ The question remains whether, statute or not, the comment rule, approved by California, violates the Fifth Amendment.We think it does. It is in substance a rule of evidence that allows the State the privilege of tendering to the jury for its consideration the failure of the accused to testify. No formal offer of proof is made as in other situations; but the prosecutor's comment and the court's acquiescence are the equivalent of an offer of evidence and its acceptance. ”
