On the prowl for WMD

[Carrie]

Remember the Indiana Jones movies where you weren't supposed to touch anything when you went into a tomb, because it was covered in a light powder that was a poison?

This morning forces found weapons with a powder sprinkled on them, they didn't plant it - the embedded reporter was there with them filming it as they found it. The news crew also went in and did their own tests on the material, and it tested positive for Ricin.
That's the stuff that kills you in 72 hours and there is no cure for it.

So, looks like the question starting this thread is moot.
