Agreed arresting them would be the just thing to do. But like all of the actions from that period their orders originated from the highest levels of the executive all the way to the Cheney and Bush. Arresting the lying CIA officials would entail carrying out a serious and rigorous investigation led by a competent Federal Prosecutor. The whole process was so muddied by politics, revenge and utter disregard for the principals and norms of war (all covered by international treats), but also a blatant disregard for the laws of the USA. Importantly one earliest actions of the Obama administration was to disallow and essentially censor the publication of all photos of torture and ill treatment that occurred in Iraq and Afghanistan. With that action Obama’s administration instead of cleaning house, made itself complicit in all the actions of torture and extra-judicial killings that occurred under the Bush administration. Of course extra-judicial killings are still occurring today under Obama with the executors being the remote pilot of the drones.
