First, torture needs to be defined. I would to include, in the definition of torture, an act that causes permanent physical scarring and/or damage. That to me is wrong. I however would have absolutely no problem with the controlled use of beatings, starvation, dehydration, water boarding, humiliation, etc. in order to extract useful information.
Herein arises the next problem though. How does one assure that the info they are obtaining is useful or even accurate?
Less focus needs to be applied to the interrogation of prisoners, especially in a war against religious radicals. More focus needs to be on extracting accurate and timely human intelligence in the areas of operation.
We need more agents, whether they are our own CIA agents or al-Qaeda or Mahdi double agents, covertly collecting real time intelligence in the field.
