There surely is a perfectly innocent explanation as to why the British government wants to buy the Skripals’ house. From George Galloway at rt.com:
Let me start with the latest: the taxpayer-funded purchase for more than one million pounds of the homes in Salisbury of the British spy Sergei Skripal and the police officer Detective Sergeant Nick Bailey. This purchase is explained as necessary on security grounds and – some suspect – may be followed by the destruction of both houses and all the evidence therein.
This is difficult to explain in the absence of a state purchase of the Zizi’s Pizza Restaurant where Skripal and his daughter Yulia ate what could have very well ended up being their last meal, and where they spent at least as much time as DS Bailey could have been in touch with the pair. Ditto the pub the Skripals visited before repairing for lunch. And anywhere else they went after leaving their door handle on which was smeared in gel form the strangely innocuous Novichok(ish) which killed none of the people who ingested it.
This presupposes that DS Bailey was never in the Skripal house but was – oddly, given his rank – merely a first responder on the park bench where the Skripals slumped at exactly the same time and in the same form, despite their differences in age, height, and physical form – itself difficult to understand if both were affected by the Novichok(ish) several hours before from the doorknob.
Neither Skripal showed any signs of having been affected in the pub, or wherever else they visited en route to Zizi’s, or in the restaurant, or even in the only short piece of CCTV footage seen in the public domain after they had left the restaurant but before they reached the park bench on which they slumped five hours after leaving their doorknob.
