The Targeted Killing of US Citizens

The Obama Administration used drones to kill three American citizens located in Yemen, including a 16-year-old boy. No trial. Not even judicial review. The Obama Justice Department has given intelligence committee members in the House and Senate access to a long-classified legal justification for killing Anwar al-Awlaki, an American citizen identified with al-Qaeda in Yemen. The move this week followed a white paper being leaked to a reporter that says civil rights can be ignored if there's an "imminent threat" of terrorism against the US. But Constitutional scholars and others see twisted logic, the redefinition of language—and a stunning overreach of the President's powers. What constitutes an "imminent threat?" Who makes the decision?  What does the CIA have to do with it?
