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".
> shocked at all if it was a lab virus
That's a useless statement. It's just a weak appeal to authority with no proof in any direction. I live in the US. Me saying that "I wouldn't be surprised" it came from the US wouldn't mean jack squat without evidence.
