Again...................did anyone bother to read the article in the OP?
IT WAS ONE F**KING INERT SHELL THAT WAS NO LONGER LETHAL.
On the first test, it was positive, but on the second test, it was negative, which is why it was sent to a lab for further testing.
They said it was inert, and they also said it was a pretty piss poor job of trying to use chemical weapons.
Sorry...............ain't much to see here unless you like crapping your pants before you cry yourself to sleep, clutching your AR-15, scared to death the terrorists are gonna get ya before you wake.
