"When Bush administration lawyers wrote their memos authorizing extreme interrogation tactics at Guantanamo, they had to conjure up horrible images: Prisoners gagging and sputtering as their interrogators reproduced the sensation of drowning. Human heads slammed repeatedly into walls. Insect-phobic prisoners cowering in fear in 8-by-10-foot cages.
How can the lawyers live with those images? And what damage did the interrogators who used the techniques sustain to their souls?
These are not academic questions for me. As a CIA interrogator in Vietnam during the last five years of the war, I know I put my soul at extreme peril. I am still haunted by what I did, and I suspect that what I witnessed and perpetrated in those years set the stage for the Bush Justice Department's approach to torture"
