"Deliberately inciting families of victims to petition?"  Oh, the horrors for the bureaucracy!  How will the bureaucrats survive criticisms that they were responsible for the deaths of thousands?  

Citizens like Liu Shaokun should be celebrated as much as that little boy who walked with Yao Ming during the Opening Ceremonies.  He will be remembered long after the bureaucrats that imprisoned him are forgotten.

More power to Mr. Liu and those like him -- he is upholding the Chinese Constitution, not the bureaucrats.  

Here is Article 41 of the Chinese Constitution:

Article 41. Citizens of the People's Republic of China have the right to criticize and make suggestions to any state organ or functionary. Citizens have the right to make to relevant state organs complaints and charges against, or exposures of, violation of the law or dereliction of duty by any state organ or functionary; but fabrication or distortion of facts with the intention of libel or frame-up is prohibited. In case of complaints, charges or exposures made by citizens, the state organ concerned must deal with them in a responsible manner after ascertaining the facts. No one may suppress such complaints, charges and exposures, or retaliate against the citizens making them. Citizens who have suffered losses through infringement of their civil rights by any state organ or functionary have the right to compensation in accordance with the law.
