Charles Krauthammer's false statement about the US Constitution | Glenn Greenwald | Comment is free | guardian.co.uk: "Now we're talking about a larger, more controversial issue: the killing-by-drone in Yemen of al-Qaeda operative Anwar al-Awlaki. Outside American soil, the Constitution does not rule, no matter how much Paul would like it to."
That italicizied claim from Krauthammer - that "outside American soil, the Constitution does not rule" - is a very common assertion and thus widely believed. But it is factually false. And there can be no reasonable dispute about this.
