I recently read what Camillo Mac Bica wrote on truth-out.org about the DOJ's white paper which purports to justify executive authority to order extrajudicial drone executions even of American citizens he determines to be a threat, however interpreted, in foreign countries. Given the lack of transparency, guidelines, oversight and accountability, however, once this authority has been acknowledged and precedent set, what would prevent such executions from occurring in this country, by means other than drones, targeting individuals other than "recognized" operational leaders of al Qaeda who, the president has determined, pose a threat, however interpreted?

The answer is NOTHING WOULD!
