Upon reflection, I'd substitute "unrevealed" for "unpunished".
Perhaps, you're correct. Punishment for crimes committed -- even against the glorious idea that is America -- might be asking too much in today's supercharged hyper-partisan era.
However, the American people have a real need to know about the crimes perpetrated in their name, but without their consent. Lay it all out on the table, let us see what was done, I say.. Let us realize what we might've lost.
