My question is how can the Obama Administration not investigate, and, if appropriate, prosecute given the world is watching, because if they do not, other may do so? How could there be "change we can believe in" if the new administration harbors war criminals – which is the way that Philippe Sands and the rest of the world, familiar with the facts which have surfaced even without an investigation, view those who facilitated or engaged in torture?
John Dean (you remember him, White House Counsel to Nixon) pulls no punches here at all. Richard Nixon famously said "I am not a crook," and to a certain level that's probably correct. I don't know that he authorized the Watergate break ins, I find it unlikely, but when he found out about them, he did all he could to cover them up.
This is a bunch of crooks, and it is not partisan to go after people who have broken domestic law and used their office to violate international treaty. The phrase is "Crimes Against Humanity" and while the previous administration may not live up to the standards of some of the prior committers of such acts, they give every appearance of having crossed that line without reservation.
