William O. Douglas

“ The failure of a defendant to deny or explain evidence against him does not, however, create a presumption of guilt or by itself warrant an inference of guilt, nor does it relieve the prosecution of its burden of proving every essential element of the crime and the guilt of the defendant beyond a reasonable doubt.' (Italics added.) ”

“ And when it is urged that it is a psychological impossibility not to have a presumption arise in the minds of jurors against an accused who fails to testify, the short answer is that Congress legislated on a contrary assumption and not without support in experience. ”

“ Certainly, despite the vast accumulation of psychological data, we have not yet attained that certitude about the human mind which would justify us in disregarding the will of Congress by a dogmatic assumption that jurors, if properly admonished, neither could nor would heed the instructions of the trial court that the failure of an accused to be a witness in his own cause 'shall not create any presumption against him. ”
