Robert H. Jackson, Stein v. New York Wissner — Opinion of the Court
“ There can be no jury trial of the coercion issue without bringing to the knowledge of the jurors the fact of confession and usually its contents. But American practice has evolved no technique for learning, through special verdict or otherwise, what part the knowledge plays in the result. Hence the dilemma of this case is always present, if not presented in earlier cases. If this uncertainty invalidates any conviction or requires an acquittal, it is a grave matter, for most states, like New York, permit no prosecution after acquittal. ”
