At least, the Executive Director does. His reasoning? Nothing is going to come of it anyway, and at least a pardon makes it clear we consider this criminal. https://www.aclu.org/blog/human-rights-national-security/pardon-bush-and-those-who-tortured I don't know about the pardon, but I do think it is unlikely any kind of prosecution will result. I don't think it likely that higher-ups in the government, on both sides of the aisle, were unaware of what was going on, and that makes it unlikely that either side is going to push for the kind of independent investigation you'd need for a criminal prosecution. The guy who oversaw the program, Jose Gonzalez, is on the record saying he personally briefed members of Congress, including Nanci Pelosi, about all of this at the time it was happening. The Senate Intelligence Committee didn't even talk to Gonzalez, who was the top person in charge of the program from its inception. Seems to me that is one of the first people you want to talk to if you want to get to the bottom of everything. The Senate report is pretty sickening, and I doubt many in Washington want it to go much further than that for obvious reasons. More likely, it is meant to be a political football released during a lame duck session, with no one wanting an independent accounting of any of it for fear of where the blood trail might lead.
