Where would terrorists get chemical weapons? There weren't any WMD in Iraq.
At some point it was reported that we found mustard gas in the Euphrates river, during routine testing of the water -- during the 2003 war. It seemed this was one way they were getting rid of it.
ON the other thread everyone was trying to come up with some poison, that would act so quickly and cause these symptoms, but nobody could, that included people doing searches.
Until michigander posted the intel info about the mustarg gas and low and behold it specifically said that it caused bleeding from the mouth and nose within two minutes of exposure.
I hope they will test the place for residue of mustard gas, not just test the food and drinks.
