The Constitution of the United States, and especially the Bill of Rights contained in the first 10 (or more exactly, first eight) amendments, flatly contradicts, in letter and spirit, the Shari'a, that is the Holy Law of Islam. This does not prevent Muslims in the United States from becoming quite adept at invoking, and exploiting in any way they can popular misunderstandings about, what the Constitution permits the government to do. Look at the ACLU, and what it takes an interest in, and how many of its personnel turn out, nowadays, to be Muslims determined to further the cause of Islam, and not terribly interested in  the survival of the Constitution, or for that matter of the Universal Declaration of Human Rights.

You will not be surprised to learn that Ron Paul, too, is greatly alarmed and outraged by the killing of Al-Awlaki. Presumably, if only Al-Qaeda recruited even more Americans,American forces would not be allowed to kill them but only to try -- in the most hellish circumstances -- to capture them and bring them back to the United States for trial. The absurdity and impossibility of this is obvious to all those who are not fellow-travellers, like Ron Paul -- the reasons for his behavior can be understood if you recognize his longstanding antipathy to Israel -- and to Defenders of the Faith, so many of whom now have jobs, and important ones, at the ACLU.

Leon Panetta was having none of this, Al-Awlaki, he said, was taking part in a war against the United States, against Americnas. .He gave instructions on the justification for murdering Americans to Major Nidal Hassan, who faithfully carried out what Al-Awlaki suggested. He urged others to do, and recruited and trained the Nigerian who has entered history as the underpants bomber.

Would an American found fighting for the Nazis, or a whole regiment of American citizenss found fighting for the Nazis, be immune from kililng by American soldiers or American agents because that was an "unconstitutional" thing to do? It's absurd.

Al-Awlaki, and any Musilm who engages in a war against the United States, whether a citizen or not (and it hardly matters, given the sole loyalty to Islam that not only the "extremists' but all Muslims are supposed to show, and to obey man-made Infidel laws only when these do not conflict with the Sharia, or when they must do so to further, prudentialy, the long-term interests of Muslims, and of Islam. They are permitted to make an outward show of compliance, to "smile, and smile, and be a villain," if that display of Taqiyya or Kitman prevents Infidels from grasping the nature of Islamic beliefs, or the attitudes, inculcated in Islam, of Muslims who are faithful to the Total Belief-System that is Islam. 

He's dead. And Samir Khan are dead. And there are many others who, while they prefer to conduct Jhad using methods that are less sensational and no doubt more effective, should never have been allowed to enter this country, to live in this country , to settle deep behind what they are taught in Islam to regard as enemy lines, the lines delineating Dar al-Islam. The large-scale presence of such people in this country, or in any of the Infidel lands, has for the indigenous non-Muslims and for the non-Muslim immigrants (including those fleeing persecution in Muslim lands) has created a situation of unpleasantness, expense, and physical insecurity that would not exist without a large-scale Muslim presence.

Nothing is immune from being turned into a weapon of Jihad, and that includes the deliberate misreading of the Constitution, and the attempt to make it, as Mr. Justice Jackson said we are not obligated to make it, into "a suicide pact. "
