How do I know this?
Simple: we classify information to protect one of two things: Sources and methods.
By releasing the memos, President Obama already decided to let everyone know both source (the terrorists, like KSM) and the methods (waterboarding).
There’s nothing left to protect.
So why doesn’t he release the facts on what valuable information was gained from the waterboarding? Why doesn’t he release the facts on what plots were actually foiled due to information gained from the waterborading?
Why, if not for political benefit for himself and Democrats?
