All the earmarks? Please. It was a truck bomb. On a soft target. Whoopee. So I guess AQ did Beirut, too? Or OKC?
An earmark for AQ is long-term planning for coordinated attacks. This could have been just as easily have been a PO'd Special RG commander with access to C4.
Having said that, I think AQ terrorists/trainees were involved here and in various attacks throughout Iraq. You completely missed the point of my post.
