Nicholas Wade (former NYTs science reporter) has written a thorough article analyzing the possible sources of the Covid virus. One of his conclusions is that it is reasonable to argue that it was created at the Wuhan lab, which was funded by the US, which would also bear responsibility. Personally, I have no dog in this fight, but because I think there are a number of knowledgeable people here, I believe some people might be interested and some might have interesting nuggets to add.
If this ends up at the test board or gets nuked, no big deal to me.
Here is the main take away:
"It’s documented that researchers at the Wuhan Institute of Virology were doing gain-of-function experiments designed to make coronaviruses infect human cells and humanized mice. This is exactly the kind of experiment from which a SARS2-like virus could have emerged. The researchers were not vaccinated against the viruses under study, and they were working in the minimal safety conditions of a BSL2 laboratory. So escape of a virus would not be at all surprising. In all of China, the pandemic broke out on the doorstep of the Wuhan institute. The virus was already well adapted to humans, as expected for a virus grown in humanized mice. It possessed an unusual enhancement, a furin cleavage site, which is not possessed by any other known SARS-related beta-coronavirus, and this site included a double arginine codon also unknown among beta-coronaviruses. What more evidence could you want, aside from the presently unobtainable lab records documenting SARS2’s creation?
Proponents of natural emergence have a rather harder story to tell. The plausibility of their case rests on a single surmise, the expected parallel between the emergence of SARS2 and that of SARS1 and MERS. But none of the evidence expected in support of such a parallel history has yet emerged. No one has found the bat population that was the source of SARS2, if indeed it ever infected bats.

First and foremost, Chinese virologists are to blame for performing gain-of-function experiments in mostly BSL2-level safety conditions which were far too lax to contain a virus of unexpected infectiousness like SARS2. If the virus did indeed escape from their lab, they deserve the world’s censure for a foreseeable accident that has already caused the deaths of 3 million people.
True, Dr. Shi was trained by French virologists, worked closely with American virologists and was following international rules for the containment of coronaviruses."
