What. The. **censor**.
I study Biological and Chemical Warfare.. Whenever someone starts with chlorine ANYTHING, something is up. I'm strongly against Senator Sanders, but this is way WAY too far.
The number one thing that pisses me off more than anything is the use or attempted use, research, manufacture, or stockpiling of chemical weapons or their precursors with or without intent of deploying them on civilians. Given the chance, I would beat to death anyone using, attempting to use, or planning to use them on or around civilians.
