"There is no lab leak theory," as Jonathan M. Katz so ably notes.
When you look at the various lab leak theories, which is that the there was an accidental leak of the virus, strengthened by gain of function experiments, from the Wuhan Institute of Technolgy, it turns out that there really is no coherent theory.
First, people conflate the Wuhan Institute of Virology, which was about 15 km from the wet market, and the Chinese CDC lab, a few hundred meters from the wet market where the first 2 (at least) outbreaks occurred.
The thing is, if it did leak from the latter lab, it would have been a natural virus, because the CDC lab does not do gain of function tests.
Of course, that would not explain why the first TWO outbreaks (the first one did not "take") occurred at the wet market, as opposed to, for example the households of CCDC or WIT staff.
As an FYI, Mr. Katz, has some significant priors in reporting about disease outbreaks, as he is largely responsible for the revelation of the source of the introduction of Cholera to Haiti by UN troops.
It goes on from there:
………
Given that experience, you might think I’d have been among the first
to buy into the allegations of the “lab leak” origin of COVID-19.
Indeed, I’ve heard through the grapevine that some of my old Haiti
cholera crew are buying the hype. But I’m not. At least not yet. That is
because the lab leak is still missing the key element of the U.N.
cholera story that made it more than just a bunch of rumors: an actual,
coherent theory of the case that could be refuted or confirmed.
When
you peel back the label, it seems “lab leak” is a jaunty alliteration
that papers over a variety of wildly different, often mutually
exclusive, ideas. It isn’t a theory but a bundle of loose hypotheses
that contradict each another on basic facts: the nature of the virus in
question, the timeline of introduction — even the identity of the lab at which the alleged leak occurred.
………
So first, let’s get something out of the way. A
pair of incontrovertible facts underlies most of the lab leak
narratives: SARS-CoV-2, the coronavirus that causes COVID-19, was first
detected in the city of Wuhan. And there is at least one lab that
studies coronaviruses in Wuhan.
But that is not a theory.
It isn’t even a hypothesis. It’s just a vibe: two facts, possibly
correlated, possibly not, that are a good jumping-off point for
formulating a question. And, to be clear, it is a valid question! Though
it is a question that has been asked, repeatedly.
On Friday, the Wall Street Journal spurred the newest round of question-asking when it published a front-page story headlined: Lab Leak Most Likely Origin of Covid-19 Pandemic, Energy Department Now Says.
………
I probably don’t have to tell you that was all bullshit. But I will
anyway. For one, there is nothing in there about a “Chinese military
biolab” in the WSJ story. In fact, the WSJ flatly refuted that entire
line of speculation, noting: “the update reaffirmed an existing
consensus … that Covid-19 wasn’t the result of a Chinese
biological-weapons program, the people who have read the classified
report said.”
………
The WSJ had no idea. The reporters did not actually see a copy
of the five-page report; the unnamed officials who told them about it
“declined to give details.” (FBI director Christopher Wray repeated his
agency’s conclusion in a Fox News interview Tuesday, also refusing to
provide details.) But CNN claims to have the goods:
Three
sources told CNN that the Department of Energy’s shift was based in
part on information about research being conducted at the Chinese
Centers for Disease Control in Wuhan, China, which was studying a
coronavirus variant around the time of the outbreak.
Take
a closer look at the name of the lab in that quote. If you have been
reading anything about the lab leak for the last three years, or even
just looking at the pictures, you will no doubt recognize the name Wuhan
Institute of Virology.
Well, it may interest you to know that the Chinese Centers for Disease Control [and Prevention] is not the
Wuhan Institute of Virology. It is, in fact, an entirely different
institution — nine miles away, on the other side of Wuhan, across the
Yangzi River. To put it in American terms: If the CCDC was near the
White House, the WIV would be somewhere in Falls Church, Virginia.
………
As it happens, switching the lab at the center
of the story would solve one big problem the lab leakers have been
struggling with for three years: that the earliest known cluster of
COVID cases was nowhere near the WIV. During the initial wave of
unexplained pneumonia, doctors immediately identified the Huanan Seafood
Wholesale Market, on the west side of Wuhan, as the common link. That
was why, to the chagrin of investigators since, Chinese officials
immediately closed and sanitized the market on January 1, 2020. Since
then, evolutionary biologist Michael Worobey and his colleagues have
provided even more detail for the case that the market was the “epicenter” of the pandemic.
………
The irony is that the very DOE story Carlson was piggybacking off of fits better with the market being the first major site of contagion. That’s because, while the Huanan market was far from WIV, it was very close to the CCDC. So, points for the lab leakers, right?
Maybe,
maybe not. While switching out the lab does solve the distance issue,
it creates bigger problems for the lab leakers. That is because it would
probably invalidate their most cherished idea: that the virus not only
escaped from a lab, but was engineered in one.
The
problem here is that, while WIV does have a history of doing
potentially dangerous gain-of-function research, all indications are
that the CCDC in Wuhan does not.………
………
Is the theory that the reported three sick WIV workers carried
the virus to a nearby hospital? Or are they irrelevant, which is why
they don’t even bear mentioning in the Republican House Intelligence
report? How can Chan and Ridley — who wrote an entire book implicating
the Wuhan Institute of Virology — shift seamlessly to offering evidence
that a totally different facility
was at fault? Does Carlson think the FBI and DOE are lying deep staters
when they say COVID wasn’t a bioweapon, but telling the truth when they
say — for apparently different reasons! — that they think it is most
likely that it came from … some lab? Somewhere?
Contrast
all of that to the parsimony of the market hypothesis: In a city of 11
million people, bigger than all five boroughs of New York City combined,
the first known cases were clustered around a single market. That
market housed caged mammals capable of contracting and spreading
SARS-CoV-2: animals farmed
in areas suspected of being a source of the virus. The samples taken
from the surfaces on the area where the animals were housed tested
positive for SARS-CoV-2. Vendors and customers at the market got
infected, they brought the virus home and to jobs elsewhere, and soon it
spread across Wuhan, and then the world.
That story is not
without holes: most notably, researchers haven’t yet produced the
intermediary species needed for it to work. But it is coherent, clear,
and more importantly, testable. (It also happens to be a story that
resembles the way nearly every other viral epidemic in human history
began, including the original SARS-CoV-1 in 2003.)
It's not just that there is little if any evidence of the outbreak originating from labs, it is that there are many conflicting lab leak theories, and none of them have little if any evidence backing them up.
