I don’t think Obummer consulted Congress on this killing of an American citizen either.....
FTA:On how the Obama administration justifies the drone strike that killed Awlaki
The kind of core argument is that Anwar al-Awlaki was posing a continuing, imminent threat to Americans, to the United States, and that while he was entitled as an American citizen to due process under law before they deprived him of life or liberty, which is what the Constitution says, that you could give due process by simply an internal, executive branch, secret examination of the evidence against him. Normally we think of due process as your day in court, your right to confront your accusers, to be charged criminally, to be judged by a jury of your peers and so on, but what ... Obama’s Justice Department decided was that it was adequate due process for the CIA and other agencies to sort of assess what Awlaki had done, to judge him to be an imminent threat and that would justify his killing.
Alwaki is a great example of reasons to end both birthright citizenship and dual citizenship. No one can serve two masters.
