Any chemist would know that phosphorus oxychloride is a chemical intermediate in the synthesis of organophosphate pesticides. OP's are post-synaptic uptake inhibitors (nerve toxins), originally synthesized by I.G. Farben.
What were the barrels of chemicals found in Saddams bunkers that we were told were harmless pesticides? It would be interesting if this guy is being prosecuted for the same things that we were told was not evidence of WMD.
