The Government has been blocking online comments about Bo Xilai and his wife, who is accused of the murder of Neil Heywood, which tells you something about how sensitive this case is.
The circumstances around Neil Heywood's life and death have exposed details about the privileged life of party officials, and that has been very damaging. How could Bo Xilai on a relatively low state salary, send his son to an exclusive English public school?
It's damaging and the Communist Party knows that. The president has made a speech saying that corruption is the biggest threat to the Communist Party's continued power in China. This investigation is under unprecedented public scrutiny.
