This frightens me for our troops. Remember the school where the WMD were supposedly buried under a hastily-poured concrete slab? Did you ever see the excavation of that site?
I work in the Hazardous Materials field. It is SOP to suit up when you go into an UNKNOWN chemical environment. The troops that were digging that concrete slab up weren't wearing any respirators, no gloves, no eye protection, etc.
All it would have taken is one backhoe scoop into the side of a 55-gallon drum of the wrong stuff... and then every one of them could have been dead.
As it turned out, they "said" there was no smoking gun. LOL... but my point is not whether or not they found anything... it's that they were investigating an UNKNOWN but suspected WMD site. They MUST wear full MOP gear when investigating WMD sites. They can always dress down after the initial investigation... but you can't go back once you've been exposed.
