Kim Jong-nam was killed with nerve agent

I do wonder just how positively identified this actually is… The amounts of agent are going to be tiny, and the sorts of field-testing techniques/kits are really only used to confirm that something IS a chemical agent and what kind of treatment is indicated. So while it’s important to distinguish between, say mustard agents (H agents) and V agents finding out exactly which of several chemically similar agents are involved isn’t necessary.
And almost all chemical agents are liquid at room temperature.
