''The other thing, which makes me very curious, the man, had a family and was well educated. A very unusual candidate for a suicide.''
Not really. As were most of the 9/11 hijackers, in fact Western educated. As is Bin Liner. As is Zarqawi.
More important, where did the explosives come from? The Land Cruiser was pretty well loaded by the look of the blast. Who fitted them and the dets? I assume it was a local 4WD so it was done locally, and quite expertly. Those individuals are still out there, possilby with more.
