Whether a confession allegedly produced by the administration of scopolamine and phenobarbital states a federal constitutional claim of involuntariness.
Holding
Yes. If drugs caused Townsend's confession rather than a rational intellect and free will, the confession was constitutionally inadmissible.
Reasoning
The Due Process Clause excludes a confession whenever the defendant's will was overborne or the statement was not the product of a rational intellect and free will. That rule applies equally to physical coercion, psychological pressure, and drug-induced statements.
The interrogators' knowledge or purpose is not controlling. Even if officers or the doctor did not understand scopolamine's possible “truth serum” effects, a confession is inadmissible if the drug in fact deprived the accused of free choice.
Townsend's allegations, if proved, could establish involuntariness. The relevant context included his youth, addiction and withdrawal, low intellectual functioning, lack of counsel, the timing of the injection and confession, and his rapid confessions to multiple crimes after treatment. The Court did not decide whether those allegations were true; it held only that they stated a constitutional claim.
