According to info found, see:
http://www.au.af.mil/au/awc/awcgate/crs/rl33662.pdf regarding changes tabled and passed through Congress Bush2 may have a get-out-of-jail (or noose) free card.
But seems to me and I could be wrong, a few Nations have filed a complaint against Bush2 in the world court. Under the War Crimes Act deliberate omission of the Use of Torture regulations of the Geneva Convention.
Would be interesting to learn Pres Elect Obama's position on any potential Presidential Pardon of the to be Former US Pres G W Bush?
