I watched that very interesting interview with the Proff. He was very relaxed about how the investigation was progressing and to the frustration of Andrew Marr he was not going to infer any direct blame.
Yes indeed! Spot on fella. Marr behaved; throughout the entire interview with the Prof; as a shit-stirring little toad.
I might be wrong but I inferred from the Prof's interview that the WHO team's investigation had virtually ruled out a leak from the Wuhan BSL4 lab.
One assumes for the team to make that assumption they must have analysed the genetic codes of the viruses being studied at the lab and found none remotely matched the SARS-Cov-2.
By that I mean a closeness of resemblance of, say, 80% and above.
This is of course the claim that 'batwoman' Shi Zengli, one of the head scientists at the lab, had made all along.
The Marr programme made reference to four main 'theories' or possibilities, but then, frustratingly, didn't elaborate to any forensic degree on them.
But one I picked up; that I hadn't heard before; was that the virus originated outside of China and was imported into the country in frozen food.
This 'frozen food' theory is highly unlikely in my view, as the implication is that the Huanan Seafood market would be one of the first places to receive this frozen food.
Yet it has been confirmed that several of the first patients in Wuhan to be afflicted with the viral pneumonia in Nov/Dec 2019 had absolutely no connection with the seafood market.
So the 'frozen food' theory is a non-starter in my book.
I think it is just being put out there to keep alive the possibility that the virus was 'imported' into the country, and did not actually originate from there.
