Introducing the idea of public mass protest to kids. Imagine the press if 'something bad' happened at the protest when little Jimmy & Jane are involved & get hurt… The kids could do anything - are the cops going to stop it with batons & water canon? No.
The speed with which Porton Down (Brit chem/bio warfare establishment) identified the nerve agent by name & 'Russian-made", tells me they either physically possess the nerve agent or at least have the chemical formula. The claim that "only the Russians" possess the nerve agent is pure crap. I believe the same nerve agent was used in Feb 2017 to assassinate Kim Jong-Un's half brother, Kim Jong-Nam in Malaysia.
