CNET reports that a Chinese woman was arrested on her wedding day for a re-tweet she made referring to a sarcastic tweet her husband made about a dispute between China and Japan.
According to the Huffington Post, China and Japan are diplomatically feuding which led to an urging of Chinese Nationalists to smash up the Japanese pavilion at the Shanghai Expo.
The woman was charged "for disrupting social order". Twitter is illegal in China.
Although this may be more of a human rights issue rather than an ethical issue, I feel that this is an important issue. In some way, I feel that both human rights and ethics have a close tie.
