interest news about two Russians apparently visiting Skripal on March 4. Arrived at train station at 11:48, walked towards Skripal house, seen on CCTV at 11:58. Next seen on CCTV at 13:05 near town center, back to train station at 13:50. Skripals seen on A360 at 13:35, then 
2/ then at Sainsbury parking at 13:40, feed ducks at 13:45, then to Zizzis and Mill Pub (inconsistent versions of order), collapse on park bench at 16:15. Window for Russians at Skripal house is about 12:05 to 12:45. Police say they sprayed doorknob. Wonder if they met Skripal?
3/ if Skripals were inside house at time and left just prior to A360 sighting, then both must have touched outside doorknob on exit at say 13:20 - note: usually only one person in party shuts door, but maybe they forgot something.
4/ Skripals arrived downtown more or less as Russians were leaving train station. So if Skripals were actually poisoned while they were downtown, the Russians have an airtight alibi.
5/ police theory is that fast-acting nerve agent had no effect on Skripals for three hours after touching doorknob, then simultaneously and suddenly felled both father and daughter - of quite different ages and health - on the park bench.
6/ I havent parsed how police connect perfume bottle to Russians. I understood that perfume bottle had been discovered in trash near park where Skripals collapsed. If so, doesn't that require Russians to have gone from Skripal house to same park prior to leaving by train? Why?
7/ seems to me that, despite the interesting new chronology, there are important loose ends in both connecting the two Russians to the collapse of Skripals three hours after they left Salisbury; and to GRU. Will be interesting to see next step.
