The latest reports are casting doubt on whether or not Adam Gadahn was actually arrested today in Pakistan. Presumably we’ll know more soon.
Late Update: The Times now says it was Abu Yahya Mujahdeen Al-Adam, also an American citizen, apparently born in Pennsylvania. Little else seems to be known about him.
I would not be surprised if this story too gets revised. It seems like there are still a lot of conflicting reports.
Later Update: The Post suggests that it’s actually still not really clear who the Pakistanis captured. They’re leaving open the possibility that it’s Gadahn, but seem to be leaning against it.
