Its called problem, reaction, solution.
Oh look Iraq has wmd's (problem) the population reacts in fear, please keep us safe (reaction) lets bomb the crap out of Iraq (solution)
The wmd's never existed and there is as much evidence to show novichok exists.
Lets put it this way:
Novichok, the most deadly toxin known to man but hasn't actually killed anyone in salisbury.
So toxic all you need is one partical on your skin and it will kill you but then look at the photos of the scene, there are people in hazmat suits talking to firemen in day uniform with open face helmets and bare hands while in the long shots there are people sat waiting at a bus stop.
So toxic that the public were having to destroy there clothes but they remove the contaminated car from the scene on a faltbed truck through the town centre.
