Syria: how UN inspectors might be able to identify the weapon AND its source.

1. More information would be great.

Obviously, there could never be 100% certainty. The thing that jumps to mind is the looting/capture of army stocks by various insurgent groups. There is more than a little fog here.

This could be a starting point, to get somehow to a high degree of certainty regarding what was used, and by whom. But then aside from that there are myriad issues about what, if anything, should be the response. And this includes contingency for if such occurrences were repeated. Another shot across the bow? Again and again? Or is the US willing to commit to actually intervene and secure all WMDs in Syria?
