From the news reports of this alleged use of chemical weapons, well that's the word the talking heads have been using, "alleged"...
It must be some cheap Sarin gas, because even a small drop of Sarin on your skin is enough to make you do the dying cockroach dance and kill you if you don't have an Atropine injector handy. There shouldn't be any video of sickened survivors at all. That's why I think the reports are bogus BS. They're just trying to stir the public into backing a military incursion into Syria and by association, Iran. The public is so damned gullible it's ridiculous and the warmongers will use it to their advantage.
