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)
