The initial report of the arrests of two suspects caught with a "truck load of explosives" at the GW Bridge also indicated that the authorities believed the two men were terrorists intent on blowing up the GW Bridge on 9/11, but as far as I know, we never heard any follow up afterwards in the mainstream media as to what happened to the suspects or any information as to whether or not they were part of the 9/11 conspiracy involving the Muslim hijackers.
