Felix Frankfurter,
Adams v. United States ex rel. McCann…
“ Were we so to hold, we would impliedly condemn the administration of criminal justice in states deemed otherwise enlightened merely because in their courts the vast majority of criminal cases are tried before a judge without a jury. To deny an accused a choice of procedure in circumstances in which he, though a layman, is as capable as any lawyer of making an intelligent choice, is to impair the worth of great Constitutional safeguards by treating them as empty verbalisms. ”
