"RYAN CHILCOTE, CNN CORRESPONDENT: Well, Wolf, we are actually at that ammunition plant, as you said near Karbala where the 101st believed, and as you said -- said on our air yesterday, that they had found chemical dual use chemical and biological laboratories buried under the ground here.

That was, it turns out, not entirely accurate. A team of experts from the Mobile Exploitation Team Alpha, some of the best experts from the U.S. Army here in country, have been working at this site tirelessly for the last few days. And they have found that there are no chemical and biological laboratories here."

Perhaps the media should check its facts a little more carefully before declaring that the smoking gun has been found.
