I'm not to prove anything in a court of law; I'm deciding what to believe. I can only believe they're innocent or they're guilty, and I'm going with the weight of probability that it's suspicious.
I believe it's suspicious, but it's not the Russians I'm suspicious of.

What's your proof of this?
lol the word "novichok" is no longer on the Porton Down wikipedia page, and vice versa. I'll find something, bear with me.
