A terrorist is on trial. The key witness is not allowed to testify since his identify was revealed as a result of torture. The terrorist might possibly be acquitted. As Glenn Greenwald points out, the neocons are angry at Obama for subjecting us all to the inconvenience that is due process.
And of course they are also angry at the assholes who tortured the guy and botched the case in the first place. Finally faced with potentially adverse consequences of torture - a terrorist could be acquitted - they insist on investigating the torture regime of the previous administration.
A man can dream, no?
