The letter shows the time old issue 'who polices the police', it reads very defensively, if ecoalliance and the lab were responsible they're not going to offer up the evidence that proves their guilt. The fbi couldn't do a swoop on the lab, and seize all the data and computers/equipment.
While it might appear that the similarity of RaTG13 and BANAL-52 bat coronavirusesto SARSCoV-2 is close because it overlaps by 96-97%, experts agree that even these viruses are far too divergent to have been the progenitor of SARS-CoV-2. For comparison, today’s
human genome is 96% similar to our closest ancestor, the chimpanzee. Humans and chimpanzees are thought to have diverged approximately 6 million years ago.
Their honesty and integrity must be doubted, as they never disclosed any of this Gof work using bat viruses had been undertaken and funded. It's required outside individuals to dig to get Nih to admit this much.
