It's Alright, we got Special Permission

Director of National Intelligence Dennis C. Blair said in each case a decision to use lethal force against a U.S. citizen must get special permission. . . .

But even if you’re someone who does want the President to have the power to order American citizens killed without a trial by decreeing that they are Terrorists (and it’s worth remembering that if you advocate that power, it’s going to be vested in all Presidents, not just the ones who are as Nice, Good, Kind-Hearted and Trustworthy as Barack Obama), shouldn’t there at least be some judicial approval required?PG
