“A free and voluntary confession is deserving of the highest credit, because it is presumed to flow from the strongest sense of guilt . . . but a confession forced from the mind . . . .”

“A free and voluntary confession is deserving of the highest credit, because it is presumed to flow from the strongest sense of guilt . . . but a confession forced from the mind by the flattery of hope, or by the torture of fear, comes in so questionable a shape . . . that no credit ought to be given to it; and therefore it is rejected.”
