One thing I did not realize is that US researchers who conducted gain of function research tried to downplay and discredit the possibility of the virus originating from the wuhan lab. There was an anti-lab theory Lancet statement signed by scientists, and "Daszak had not only signed but organized the influential Lancet statement, with the intention of concealing his role and creating the impression of scientific unanimity."
Plus there's all the stuff about the miners shoveling bat poop for weeks and then dying of coronaviruses, and the Wuhan institute collecting and doing gain of function research on these similar-to-SARS samples. And then several of the lab's gain of function researchers became ill in late 2019. And there's the weird renaming of samples to hide the unmatched closeness of the mine samples and covid. This is just the absolute surface of the article. There's too much to list here
Edit: here's another amazement for the list: "Shi Zhengli herself had publicly acknowledged that, until the pandemic, all of her team’s coronavirus research — some involving live SARS-like viruses — had been conducted in less secure BSL-3 and even BSL-2 laboratories." And the article says "BSL-2 [is] roughly as secure as an American dentist’s office."
There is _very_ high probability that this is just a human error.
The highest probability is this virus originated like every other virus in history.
If an outbreak were to happen in the United states just about everywhere would be near a CDC location: https://www.google.com/search?client=firefox-b-e&tbs=lf:1,lf...]
You've artificially limited the number of possible labs to those doing bioweapon research. If this isn't your claim there is no reason to do so and if there are more labs studying coronavirus it's far less coincidental.
In any case, beyond gain-of-function, the WIV and Wuhan CDC also had the biggest program in the world to sample novel SARS-like coronaviruses from nature, from remote bat caves that no other humans had any reason to enter.

If SARS-CoV-2 is a naturally-evolved virus accidentally released by scientists, then Wuhan is the obvious place for it to emerge. That could have been directly from a lab, or a researcher could have become infected on a sampling trip, traveled home from the sampling sites (~900 miles away, to be clear; Wuhan was not an expected natural spillover region), and seeded the infection there. None of this is anywhere close to proven, but the previous dismissal of any unnatural origin as a "conspiracy theory" was an outrageous, unscientific smear.
How do I square that with this claim from the article?
> Eleven of its 23 coauthors worked for the Academy of Military Medical Sciences, the Chinese army’s medical research institute. Using the gene-editing technology known as CRISPR, the researchers had engineered mice with humanized lungs, then studied their susceptibility to SARS-CoV-2. As the NSC officials worked backward from the date of publication to establish a timeline for the study, it became clear that the mice had been engineered sometime in the summer of 2019, before the pandemic even started. The NSC officials were left wondering: Had the Chinese military been running viruses through humanized mouse models, to see which might be infectious to humans?"
What this describes seems like it could be circumstantial evidence of the PLA developing bioweapons. Certainly it isn't proof of anything, and as evidence it's not very strong. But I wouldn't call it 'zero.'

So if the Chinese military had in fact been doing this, I'd guess it was just basic research, in the same way that lots of American basic research links back to DARPA. Of course they fund it because they believe there might be a military application, but I see no reason to think that application would be bioweapons (vs. the same kind of beneficial applications described in the open literature).
They don't seem like obvious candidates to me, though. Both SARS v1 and SARS-CoV-2 show unpredictable, stochastic person-to-person spread, via super-spreader events. For a bioweapon that would ideally infect all the enemy but no one else, that's the last thing you want, hard to reliably get started and hard to reliably stop once it starts. So that reinforces my belief that if SARS-CoV-2 was of unnatural origin, it was almost certainly an accident during basic research.
