I found this to be an extremely engaging read and compelling story.
TLDR; The likelihood of it being lab related is high. The likelihood of it being directly malicious low.
My Take form reading it: The lab in question needed to collect bats for research. A person who collected the bats did so with insufficient safety and is likely patient 0.
So, its not quite as simple as a collection mistake.
And this sounds like a reasonable possibility to be explored. Accidents happen. Lapses in procedures happen.
The problem is that early on, and still in some circles, lab related equates to malicious bio-weapon and/or China purposely attempting to destroy the world. It's important to separate the two, and hopefully this is a cautionary tale for all labs to review their policies and procedures.
Well that's the problem with reducing every argument to absurd extremes.
It's part of why modern political discourse is fundamentally broken.
We counter discourse out of fear of what the extreme form of that accusation will be - not based on what the argument is actually saying.
Here is a direct link to some gain of function research being done at the lab for anyone interested: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2258702/
Relevant line in abstract:
> In this study, we investigated the receptor usage of the SL-CoV S by combining a human immunodeficiency virus-based pseudovirus system with cell lines expressing the ACE2 molecules of human, civet, or horseshoe bat.
This is all circumstantial, of course. But, that combined with the fact that COVID originated in Wuhan, thousands of kilometers away from the bat caves of Yunnan province, yet in the same city as the only BSL-4 laboratory in China, that's hard to ignore.
Military-funded scientific biowarfare research should be different (use different, more advanced, tools) than run-of-the-mill bioinformatics research which US scientists work with. So if the scientist is not working on military research, their guess is as good as: "it was not engineered using common industry-standard known methods". It is misattributing authority, like quoting bio science experts saying "COVID can't be a weapon because the mortality is too low". No, you have zero idea about the military applications of biowarfare. If the scientist really was a military researcher, then they won't disclose signs of tampering to a news outlet or academic journal.
Another is that, for obvious reasons, military research would like to obfuscate its engineering. So it is unlikely they use easily detectable methods for that. It is perfectly possible to breed viruses in a lab, inside natural hosts. Then you won't see any biological markers of tampering, but the virus was still engineered by cross-breeding captured fruit bats or manually creating a zoonotic transmission chain to humans. So even without biological signs of tampering, the lab leak remains plausible.
IMO the CCP is evil because they have internment camps just like Nazi Germany. https://www.pbs.org/newshour/features/uighurs/
