Opinion: the fact that the Scripal case is unclean indicates one feature

The media claim that they learned about the possible surveillance of Ruslan Boshirov and Alexander Petrov for Sergey Skripale in the Czech Republic in 2014. Alexander Vavilov, Professor of the Diplomatic Academy of the Ministry of Foreign Affairs of Russia, commented on this new version on the radio Sputnik.
Accused by the British authorities of the poisoning of the former GRU Colonel Sergei Skripal and his daughter Yulia, the Russians Alexander Petrov and Ruslan Boshirov secretly visited the Czech Republic in October 2014, where Skripal himself was supposed to arrive at the same time to meet with representatives of the Czech special services. This is reported by Prague Radiojournal, citing its sources in the special services.

"Sources from which Radio magazine received this information are convinced that this pair of Russians was already watching for Skripale," the report says.
The publication claims that Petrov from 13 to 16 October 2014 lived in a hotel in the city of Ostrava in the north-east of the Czech Republic, and then moved to Prague. According to Radio Journal, Boshirov visited Prague on October 11, 2014.
According to the publication, the stay of both Russians in the Czech Republic later engaged in both the special services and the National Directorate for Combating Organized Crime (NDIAB).
The Security Service and the National Bureau of National Security and Information Security do not confirm this information.
In turn, the Russian embassy in Prague forwarded the question of the presence of Petrov and Boshirov in the Czech Republic to the relevant Czech authorities.
Alexander Sp. Vavilov, Doctor of Historical Sciences, professor at the Diplomatic Academy of the Ministry of Foreign Affairs of Russia, commented on a new version of the media on Radio Sputnik.

According to the British side, a former GRU officer Sergei Skripal and his daughter Yulia were poisoned on 4 March in Salisbury, which provoked a major international scandal: in London they were immediately rushed to blame Russia for this.
Moscow has repeatedly offered to conduct a joint investigation, but Britain ignored this initiative. Also, the Foreign Ministry caught the British Prime Minister Teresa May in a lie: she claimed that the poison had been made in Russia, but the Porton Down laboratory had denied it.
Later, London presented photographs of the two "suspects", claiming that these were GRU officers Alexander Petrov and Ruslan Boshirov, later the men themselves told in an interview with Sputnik and RT chief editor Margarita Simonyan that they visited Britain as tourists and are not associated with special services.
