US approved use of dogs on Guantanamo prisoners:

Pentagon lawyers said torture was OK as long as it was "in good faith"!

"In December 2002 Mr Rumsfeld approved tactics such as forcing a detainee to stand up for up four hours, forced isolation for up to 30 days, deprivation of light, use of 20-hour interrogations, removal of clothing, forced shaving of facial hair, 'inducing stress by use of detainee's fears (eg, dogs)' and use of mild physical contact that did not cause injury.

A Pentagon legal brief recommending the use of the tactics argued that the proposed techniques were likely to pass constitutional muster as long as they were applied 'in a good faith effort and not maliciously or sadistically for the very purpose of causing harm'."

So as long as you were doing it in good faith, because you really, really believed the person was a terrorist, or might be a terrorist, or might have some good information on terrorists, or any information at all, well... no problemo!
