Hogwash. Weapons that had been found could have been displayed for proof of their existence without any explanation as to how they were found.
They did announce some of these discoveries, and they did show pictures. I remember it quite well.
It wasn’t enough for the MSM, though. They ignored it because unless there were eleventy-jillion giant nuclear bombs lines up in a row with a sign that said “Saddam’s Weapons of Mass Destruction,” it didn’t count.
