Stanley Forman Reed,
Upshaw v. United States — Dissent
“ If illegal detention, per se, is believed sufficiently likely to produce a coerced confession as to justify exclusion of such confessions as evidence, it does not require this extension of the McNabb rule to make such evidence inadmissible. A court never knows whether a confession is or is not voluntary. It bars confessions on uncontroverted proof of facts which as a matter of law are deemed so coercive as to be likely to produce an involuntary confession. ”
