If I - with a known history of blowing up buildings - put a 500 lb bomb in your basement, but claim I had NO 500 lb bombs left over at all because I used all of them up, would YOU want the bomb removed from your basement, or would YOU merely "trust" your "friend" in the next neighborhood who also claims I have no bombs at all, and if I did have bombs, it was your fault that I put a bomb in your basement.
I called the Pentagon to ask about the story and the press duty officer actually laughed when I asked him if the report was significant.
