My own experience: Don't ever trust the Chinese government on issues that could potentially involve the reputation of the party. Note that I'm not saying don't trust what CCP says, ever (sometimes they actually do good things) - just not on issues that involve anything to do with how the world might perceive them.
Which is exactly what this issue is about.
That's not to say we have compelling evidence that this was a lab virus, either. I think, for me, it's a, "we don't know, but I wouldn't be shocked at all if it was a lab virus".
It MIGHT have been possible but Occam's Razor says it's more plausible it evolved naturally and just jumped species.
FAR FAR FAR more plausible.
Occam's Razor says the only (non-vet) BSL4 lab in China, studying bat coronaviruses, several miles from known first virus reports, that has had multiple previous virus leaks, with huge information shutdown by China for a year, is the more plausible culprit.
