Stanley Forman Reed,
United States Smith v. Baldi — Opinion of the Court
“ In view of the fallibilities of human judgment regarding the same body of evidence it is inevitable that one may be doubtful, and even more than doubtful, whether in a particular case a plea of insanity was properly rejected. It is not for this Court to find a want of due process in a conviction for murder sustained by the highest court of the State merely because a finding that the defendant is sane may raise the gravest doubts. But it is our duty under the Fourteenth Amendment to scrutinize the procedure by which the plea of insanity failed and defendant's life became forfeit. ”
