         That would be my broader point --- there would have been no 
point in using a DU weapon in Fallujah.  Regular high explosives 
would provide the desired carnage and destruction.  Busby can't 
figure out that DU's nature is such that it is for use against 
armored vehicles, and not against buildings and people.

         To reiterate, it's more of Busby's lunacy, or ignorance, or 
what-have-you.  Perhaps now he will commence blustering that it's a 
bunker buster weapon.  So what?  Were bunker busters needed in Fallujah?
