|Russia has a decade long secret programme of producing and stockpiling novichok nerve agents. It also has been training agents in secret assassination techniques, and British intelligence has a copy of the Russian training manual, which includes instruction on painting nerve agent on doorknobs. The Russians chose to use this assassination programme to target Sergei Skripal, a double agent who had been released from jail in Russia some eight years previously.|
Only the Russians can make novichok and only the Russians had a motive to attack the Skripals.
The Russians had been tapping the phone of Yulia Skripal. They decided to attack Sergei Skripal while his daughter was visiting from Moscow. Their trained assassin(s) painted a novichok on the doorknob of the Skripal house in the suburbs of Salisbury. Either before or after the attack, they entered a public place in the centre of Salisbury and left a sealed container of the novichok there.
The Skripals both touched the doorknob and both functioned perfectly normally for at least five hours, even able to eat and drink heartily. Then they were simultaneously and instantaneously struck down by the nerve agent, at a spot in the city centre coincidentally close to where the assassins left a sealed container of the novichok lying around. Even though the nerve agent was eight times more deadly than Sarin or VX, it did not kill the Skripals because it had been on the doorknob and affected by rain.
Detective Sergeant Bailey attended the Skripal house and was also poisoned by the doorknb, but more lightly. None of the other police who attended the house were affected.
Four months later, Charlie Rowley and Dawn Sturgess were rooting about in public parks, possibly looking for cigarette butts, and accidentally came into contact with the sealed container of a novichok. They were poisoned and Dawn Sturgess subsequently died.
[T]here is still the case of the suspicious couple [in the Skripals poisoning case] on CCTV back in march, that very much resemble [latest poisoning victims] Charlie and Dawn!
I summarised [the photo evidence] here. Feel free to spread.
Yes, its a convincing match.
