Letters Give C.I.A. Tactics a Legal Rationale - New York Times

While the Geneva Conventions prohibit “outrages upon personal dignity,” a letter sent by the Justice Department to Congress on March 5 makes clear that the administration has not drawn a precise line in deciding which interrogation methods would violate that standard, and is reserving the right to make case-by-case judgments.

“The fact that an act is undertaken to prevent a threatened terrorist attack, rather than for the purpose of humiliation or abuse, would be relevant to a reasonable observer in measuring the outrageousness of the act,” said Brian A. Benczkowski, a deputy assistant attorney general, in the letter, which had not previously been made public.
