There was one of the leftwing legal pundits on C-SPAN recently (I think it was), but I forget if it was Turley or someone else, who was arguing that the correct punishment for torture is the death penalty, and he obviously thought Bush guilty. I don't think they'll go that far--even with all the comparisons to Pinochet, there is a difference between killing several thousand of your own citizens and waterboarding three terrorists (which is the main component of the "torture" allegation). I don't think the public would agree to having President Bush hanged for waterboarding 3 terrorists.
Don't be so sure.
A majority of "the public" thought it would be a good idea to elect an anti-American radical as President.
