We now see some letters from Bush and His Evil Minions™ to Congress saying that they could torture who they wanted whenever they wanted, because they were motivated by a noble cause, because their intent was to prevent terrorism, “rather than for the purpose of humiliation or abuse.”
I don’t think that a single nation among the torturers has ever adopted it as a technique because it gave them the jollies*, they have done for precisely the reasons that you give. They wanted information, and to prevent acts that they deemed lawless.
We need to send these folks to the Hague for a fair trial in 2009.
*Dick Cheney excepted, of course. It gives him a stiffie.†
