As usual a political tit for tack, with meaningless back and forth.
Torture doesn't work, in effect a meaningless statement in the modern world. Every one knows that. Thats why enhanced interrogation techniques is used in conjunction with other methods.
Did they even get tortured? who here has seen a technical description of each incident? Who here can then go though each incident with the various legal codes? Or are you saying that you just like Bin laden etc wants us to just act on moral codes, as long as there your moral codes.
As for legal action, that depends on each countries legal codes and the peoples involved counties legal code. As such, who's law do you follow and be responsible for, the country you are in, or the country you are from? A very stick problem if you are forced to follow your own countries laws in another land.
