I think that the execution of Zheng Xiaoyu, 62 (see previous post), was excessive. It was done to help China save face after so many American pets died from melamine in wheat gluten from China. It was unfair because corruption is a way of life in China, and one man was singled out.
In the US we have the same problem China has: our food and safety regulators disregard science and punish whistleblowers in order to benefit their patrons. An example of this was when the Food and Drug Administration delayed release of information about a mad cow case in the US. Another came when the FDA forbade any company in the US from doing more mad cow testing than that prescribed by the FDA.
