One wonders how much of the US spook-infiltrator's skills/cover were provided by Lindh to save his butt:
WASHINGTON The sheikh was a devout Muslim whose lifelong ambition was caring for the poor in Yemen, one of the world's most underdeveloped nations. Yet now he needed help himself. His health was deteriorating, and no facilities in his country were sophisticated enough to treat him. So he turned to his new friend, "Yussef," a wealthy but disillusioned young African-American. Yussef had converted to Islam and traveled to Yemen to become more devout, like the now infamous John Walker Lindh. The young convert suggested a trip to Germany, where the sheikh could both visit experienced doctors and raise money for his causes. But Yussef wasn't the person he seemed. As an American undercover agent, he was trying to trap the Muslim leader, who is alleged by the US to be a key financier of terrorism. What followed is a tale of deception, betrayal, and intrigue - and of the clashing international interests and viewpoints that make the pursuit of terrorists so complex. <snip> http://www.csmonitor.com/2003/0219/p01s01-usju.html "Undercover arrest stirs terror rift" --- Got Body Bags?
