But by failing to regulate wet markets properly, aren't they equally at fault?
Perhaps the supposed logic is that a scientist at a lab doing this sort of research probably counts as a government employee, whereas someone storing animals unhygienically would more likely be self-employed, so that makes the government less directly responsible.
I'm not sure if that distinction really matters to people who want to blame China's government, though.
Not really. It's just "bad luck" and "nature's fault". I never heard anyone angry on the Chinese government for not adding more red tape /regulation to the wet market. If that would be the case we should have seen people protesting all over the world against public markets where sanitary conditions are not the primary concern of the merchants. I believe it'a well known that more viruses are expected to jump from animals to humans. It's just a matter of time/luck. Simply put, failing to regulate wet markets does not equal to developing and releasing a deadly virus.
You forget the politics. CCP can never be wrong or do wrong. That would risk their rule. I'm pretty sure they would rather see the country burning than admitting guilt and incompetence. You can see that kind of selfish behaviour at most of the leaders(I would dare to say even in recent US history) but in an authoritan system this is made worse/more dramatic b/c there is no alternative(i.e opposition to replace leaders in a peaceful way)
