I do not believe in the physical torture, but mental torture yes. For example: I read in the newspaper that pows' were forced to listen to songs such as,"The Barney Song(I love you, you love me), We will rock you(Queen), Thunderstruck (ACDC), etc. for days on end. For one, to be doing anything that could get you in trouble and be tortured is stupidious.
If the person has admitted to knowledge, then possibly yes. Torture without proof; however, is inhumane.
