Although the act of torture is not allowed by the United States the troops in the middle east have used it against people who have been suspected of being terrorists. The trouble is that on a moral level it doesn't seem humane to submit individuals through countless cruelties in the name of justice. It seems even less justifiable if the torture leads to misleading information that might have been said by a prisoner in order for the people torturing them to stop the pain. Perhaps other methods should be developed to gain intelligence.
