Greenwald asks an important question:
What would stop a future President (or even the current one) from re-authorizing waterboarding and the other Bush/Cheney torture techniques if he decided he wanted to? Given that both the Bush and Obama administrations have succeeded thus far in blocking all judicial adjudications of the legality of these "policies," and given that the torture architects are feted on TV and given major newspaper columns, what impediments exist to prevent their re-implementation?
