(concurring in the result):
In my opinion, it is unnecessary to consider whether a threat to use a lie detector is a mere trick or an improper influence upon an accused sufficient to cloud the voluntariness of his confession. The matter was, in fact, presented to the court-martial by adequate instructions. See my separate opinion in United States v Schwed, 8 USCMA 305, 24 CMR 115. Accordingly, I join in affirming the decision of the board of review.
