"Convincing Evidence!"
From this article:
Chief U.N. weapons inspector Hans Blix said Monday he warned Iraq that it must provide convincing evidence if it maintains — as it did last week — that it has no illegal weapons programs.
Okay, maybe it's just me and my old-fashioned logic, but even if Saddam was the soul of cooperation, how the hell do you provide someone with absolute evidence that hidden weapons do NOT exist?
