Part of the case against Russia for Skripal is the chemical analysis on samples taken from the environment and from blood associated with Salisbury and the Skripals themselves which was organized and managed by thE OPCW. Their involvement provided cast iron, Gold standard forensic analysis to support what the Brits were claiming.
But based on these suppressed whistle blower accounts on Douma Was the report influenced in the a similar way? The underhand language of the OPCW Skripal reports in which the results were not specified exactly, might suggest they were. From the OPCW report on Skripal, it could be argued is consistent with no ¨Nocichok¨ whatsoever in the samples, despite how the report was portrayed in the media.
The Whistle’blowing on Douma makes this a more credible possibility.
