Kiwigrunt,

I am not sure this helps, but as a Canadian victim of rendition and torture it may help to learn what they say:
It is about time our governments realise that torture inflicts moral damage on our society, as severe as the pain felt by the people who are physically and psychologically tortured. Our reputation has been stained and tarnished enough.
His short article opens with:
To torture or not to torture, why is this question being asked in America? The answer you will receive is different depending on who you speak to.

I expect the questions asked over torture extend far beyond the comforts of American debate, although one wonders if it was Americans being tortured at home or abroad that the US public would think torture works.
