Back in the old days, when Barack Obama was one of the hopefuls trying to get his party's presidential nomination, he was asked a specific question: does the American constitution permit a president to detain US citizens without charge as unlawful enemy combatants? The would-be candidate's response was unequivocal, rejecting the idea that there was any such power. No wonder, then, that so many people were startled when it emerged last week that the Obama administration has authorised not only the detention but the "targeted killing" of an American citizen, the extremist Muslim cleric Anwar al-Awlaki.
