Glenn Greenwald marshals evidence and logic to show the absurdity of our national debate over investigating, and possibly trying, Bush-Cheney officials for torture. This post has many helpful links for online debate.
Combine press reports of approval of torture techniques at the highest level of government, with US signed and approved treaties binding us to prosecute torture, and it's clear that the law compels us to act.
The default judgment should be that we follow the law and investigate reports of torture. Wouldn't we investigate murder? It speaks poorly of us as a nation that following the law is viewed as a fringe perspective.
We must investigate the torture record and prosecute the wrongdoers.
