 I've wondered about that, too. I'm not sure what the rules are for revoking an American's citizenship. I guess Walker didn't bother to read the small print on the fourth page of his passport. For those who don't have one:

		| Loss of Citizenship Under certain circumstances, you may lose your U.S. citizenship by performing any of the following acts: 1) being naturalized in a foreign state; 2) taking an oath or making a declaration to a foreign state; 3) serving in the armed forces of a foreign state; 4) accepting employment with a foreign government; 5) formally renouncing U.S. citizenship before a U.S. consular officer overseas. For detailed information, consult the nearest American Embassy or Consulate, or contact the Office of Citizens Consular Services, Department of State, Washington, DC 20520-4818, or call (202) 647-3444 | 
	
 I'm not clear about the circumstances of Walker's capture, or the nature of his activities before he was captured. Has anybody heard for certain that he was "under arms", as the saying goes?
