A new report by the non-partisan Constitution Project concludes that, without a doubt, the United States engaged in “the practice of torture” in the years after the attacks on Sept. 11, 2001. Currently at Gitmo, 43 of the prisoners are on hunger strikes, in protest of what they see as the unethical treatment of prisoners and their indefinite detention without trial.

A 16-page memo obtained by NBC News was apparently the legal rationale for the killing of American citizen Anwar Al-Awlaki, an Al Qaeda operative. The memo is also the clearest statement yet of American policy on the use of drone aircraft.

Katherine Bigelowe’s latest film "Zero Dark Thirty" comes out in limited release this week, but critics have already honed in on what’s become the film’s most controversial talking point: its depiction of torture. Karen Greenberg, director of the Center on National Security at Fordham Law School and editor of “The Torture Papers," explains.

How did this hot issue become a non-issue? Has the country forgotten about the Patriot Act? Or do the candidates just hope that we have? Karen Greenberg, director of the Center on National Security at Fordham University's School of Law takes a closer look as part of The Takeaway's Don't Mention It Series.

Closing a controversial three-year investigation, Attorney General Eric Holder announced yesterday that no one will be prosecuted for harsh interrogation techniques carried out by the CIA that resulted in the deaths of two prisoners.

Attorney General Eric Holder outlined the United States’ legal defense of using lethal force against U.S. citizens overseas if that citizen is posing a terrorist threat. Holder’s speech, delivered Monday afternoon at Northwestern University, argued in part that the U.S. Constitution’s definition of due process defends the use of lethal force, even without the written consent of the president.

Until now, no legal defense was given for the U.S. mission in Yemen which killed al-Qaeda’s leading figure Anwar al-Awlaki. Al-Awlaki, who was born in the US, was the radical cleric who successfully took al-Qaeda’s message to YouTube.

According to a New York Times article released today, the Obama administration is planning to prosecute Guantanamo detainees in military commission trials. This follows decisions by Congress to prevent these prisoners from being brought to the U.S. and tried in federal courts.

Yesterday the first Guantánamo detainee to be tried in a federal civilian court was acquitted of all but one of the charges against him. In total Ahmed Khalfan Ghailani faced nearly 300 charges of conspiracy and murder in the 1998 terrorist bombings of the U.S. embassies in Nairobi, Kenya and Dar es Salaam, Tanzania.
