The "Two Atta" Theory - It might explain the Able Danger scandal. You know, i think he might just be right. When I started reading, I was wondering, can't there be more than one guy w/ that name? There are over a billion Muslims. Mohammed is the most common first name in the world. Isn't it just a teensy bit possible there are more than one with the same last name? Sounds like everyone is both right, and wrong at the same time.
