Sully says what we all know, but apparently refuse to deal with, at our peril:
In fact, the attorney general of the United States is legally obliged to prosecute someone who has openly admitted such a war crime [torture] or be in violation of the Geneva Conventions and the UN Convention on Torture. For Eric Holder to ignore this duty subjects him too to prosecution. If the US government fails to enforce the provision against torture, the UN or a foreign court can initiate an investigation and prosecution.
These are not my opinions and they are not hyperbole. They are legal facts. Either this country is governed by the rule of law or it isn't. Cheney's clear admission of his central role in authorizing waterboarding and the clear evidence that such waterboarding did indeed take place means that prosecution must proceed.
Cheney himself just set in motion a chain of events that the civilized world must see to its conclusion or cease to be the civilized world. For such a high official to escape the clear letter of these treaties and conventions, and to openly brag of it, renders such treaties and conventions meaningless.
