Do you believe two decorated GRU veterans used fake names and fake passports just so they could fly over here to see Salisbury Cathedral one weekend as they claim?
Who cares whether or not that is true? Only the gullible consider that a relevant question.
The amount of holes, contradictions and obvious lies in the official version of events make it plain that they were not here to murder the Skripals with the world's most lethal nerve agent either.
A nerve agent so deadly it killed no-one? It remained almost "pure" despite allegedly being left exposed for days on the door knob of the Skripals home?( Which inexplicably led to the entire roof being removed and replaced due to contamination. All hidden from view under protective screens. The door remained in place

)
After applying the deadly nerve agent ( a gel, allegedly via aerosol? from a perfume bottle supposedly discovered months later which our intrepid Russian poisoners had resealed in its box and plastic wrapping

) our highly trained GRU assassins went to do some shopping in Salisbury where they are seen a number of times on CCTV
Is it believable that our two Russian agents after carrying out a chemical weapons attack in a foreign state( a clear act of war, it should be noted) instead of immediately getting the fuck out of Dodge instead went window shopping? It is embarrassing to fall for this shit.
Anyway back to the unconvincing, made up on the hoof by idiots as they went along, story of our highly trained (but inexplicably inept) GRU assassins and their world's most deadly( but strangely ineffective) nerve agent.
After smearing the door knob (unseen despite CCTV at the Skripals) Sergei and Yulia both allegedly touched the door knob in order to become contaminated with the WMDNA and then went for a drive, a drink and then something to eat. Luckily, no one else was contaminated by the WMDNA, despite the Skripals being in very public places. Some 4 hours after contacting the WMDNA both Yulia and Sergei succumbed simultaneously to similar symptons outside the restaurant where they had just eaten.
By serendipitous coincidence the first responder on the scene of this WMDNA attack just happened to be British Army Most Senior Nurse, Colonel Alison McCourt. She gave first aid without becoming contaminated but she probably knew some magic tricks, especially with her being a specialist in chemical weapons, and still at that time taking part in Chemical Weapons exercise, Toxic Dagger, at Porton Down just 8 miles away. Check it out yourself. How lucky for the Skripals. Anyway our GRU poisoners were still window shopping in Salisbury just 500 yards away at this time.
The two, not dead, victims of the WMDNA attack are unheard from and consular access denied to Russia by the UK to Yulia who herself expressed a wish to return to Russia in her sole(stage managed by UK intel) appearance since their disappearance. If Russia were denying access to the UK in a roles reversed situation then opprobrium would be huge and rightly so. Yulia is a Russian citizen. The UK gov need to prove that Yulia has free will. Sergei also, but Yulia is not convicted of anything and is a Russian citizen. To all appearances she is being held, against her will, by the UK gov.
There are reams of commentary on the available facts that make a mockery of the official position. The above does not remotely slightly mark, never mind scratch the surface of the holes and contradictions in the UK chemical attack tall tale. For those interested in attempting to get to the truth of the Salisbury incident, there are many excellent sites that covered this(the Blogmire
