From the office of Sen. Russ Feingold, a suggestion that the administration is open to future prosecution. Do know that Feingold and other key members of Congress have been formally briefed on this, so he presumably is not thinking wishfully here:

"The president has stated that it is not his administration's intention to prosecute those who acted reasonably and relied in good faith upon legal advice from the Department of Justice.  As I understand it, his decision does not mean that anyone who engaged in activities that the Department had not approved, those who gave improper legal advice or those who authorized the program could not be prosecuted.  The details made public in these memos paint a horrifying picture and reveal how the Bush administration's lawyers and top officials were complicit in torture.  The so-called enhanced interrogation program was a violation of our core principles as a nation and those responsible should be held accountable."
