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".
Are we talking about China or the Trump administration?
The tone and tenor of the investigation has always been to find a way to absolve local politicians of responsibility for their incompetence in managing this issue by blaming China.
All for the punchline of "so you're then going to do what to China in response?" Of which the answer is nothing. The genocide of the Uyigur people certainly hasn't motivated any strong international action.
I think you have this backwards. The obsession has always been first and foremost with US domestic politics because so many americans on the internet have an unhealthy obsession with domestic politics. Present discussion is a yet another example.
There's an unsolved mystery we would like to see solved. Specifically right at the heart of one of the most traumatic and pivotal events of our lifetime. Why do you care so much about finding ulterior motives for people interested in that mystery?
