This source is not sure that it is Adam Gedahn who has been captured (see our post Treason, below):

Two Pakistani officers and a government official said Sunday that an American charged with treason for working with al Qaeda had been captured, a development that could deliver another significant blow in the U.S.-led battle against the terror network.

U.S. defense, intelligence and law enforcement officials could not immediately verify the reported detention of Adam Gadahn, a 31-year-old spokesman for al Qaeda who has appeared on videos threatening the West, including one that emerged earlier Sunday. …

Some observers were cautious about giving credence to the claim that Gadahn was in custody as reports emerged that the man arrested might instead be a Taliban militant leader. There was no way of independently verifying the arrest or identity, and detentions of terror suspects in Pakistan are often surrounded by conflicting reports.

This source is sure that the captured man is not Adam Gedahn:

The first American to be charged with treason since World War II was back in the news Sunday, both for a new videotape he released and for reports of his capture that turned out to be false. In the videotape, al-Qaeda operative Adam Gadahn, an American convert to Islam, praised the Fort Hood jihad murderer and called upon Muslims to carry out jihad attacks in the United States. The reports that Gadahn had been captured caused widespread excitement until the arrestee turned out to be a different American convert to Islam, Abu Yahya Mujahdeen Al-Adam [or Azam], who like Gadahn is an al-Qaeda leader.

No matter who he is, if he’s a traitor to America he should be executed.
