When Can Drones Kill Americans?

Danger Room article, "Senator Asks CIA Nominee When Drones Can Kill Americans," informs:  "Sen. Ron Wyden (D-Ore.) [picture, left] sent a letter on Monday to John Brennan [picture, right], the White House’s counterterrorism adviser and nominee to be head of the CIA, asking for an outline of the legal and practical rules that underpin the U.S. government’s targeted killing of American citizens suspected of working with al-Qaida. The Obama administration has repeatedly resisted disclosing any such information about its so-called 'disposition matrix' targeting terrorists, especially where it concerns possible American targets. Brennan reportedly oversees that matrix from his White House perch, and would be responsible for its execution at CIA director." When is it okay to kill Americans? It's the question on Wyden's mind, but details of the "disposition matrix" remain a secret!  "Wyden doesn’t ask for their dis- closure, just for the administration to permit members of the intelligence panel to read them," explains article. Wow!
