Are you sure?
Do you have an example of substantial disaster or scandal that resulted in loss of life and loss of face for China, but perpetuators got away?
For UK I have: Grenfell tower scandal (over 100 dead, no one in prison), infected blood scandal (thousands dead, no one in prison), postmaster scandal (thousands falsely imprisoned , no perpetrator in prison), etc.
