Depleted uranium
<Watched a network program the other day where they took some 25kg of depleted uranium, put it in a box labelled something, machine tools or something, and shipped it from Russia via Turkey to New York.
Not one hitch. Could have been wild rice for all the interest anyone showed in the shipment.
Depleted uranium is about as radioactive as wild rice, which may have been a small flaw in the test. But I would like to see our borders tightened up.
