We should instead be asking: What is the chance that a big Chinese city like Wuhan would have a lab doing the kind of research that has come under suspicion? The answer is, the vast majority of the biggest cities in China have labs involved in such research. If COVID had emerged in, say, Beijing, there would be no fewer than four such labs facing suspicion.
I remain open to any and all evidence supporting a laboratory origin of the pandemic. So far, we have no such evidence.
