Regarding [1] - while you are 100% correct concerning the manufacture of sarin gas, you are almost certainly wrong in relation to the deployment and/or activation of sarin gas in a controlled space. "Throwing a grenade" is generally considered 'low skill'. In the case of the Tokyo sarin gas incident, the gas was deployed in a plastic bag (I'm thinking zip loc) and was stabbed with a sharpened umbrella to deploy.
