Remember the case of Shi Tao? He's a Chinese journalist who was imprisoned back in 2004 for supposedly leaking state secrets by writing an e-mail to a New York-based pro-democracy group, describing how the Chinese government planned to crack down on local media covering the anniversary of the Tiananmen Square massacre.  Yahoo supplied information about Shi's e-mail address to the Chinese authorities, leading to his arrest and 10-year prison sentence.

Finally, Yahoo is issuing a mea culpa for its role in the case. More specifically, Yahoo's top lawyer is apologizing for failing to tell the U.S. Congress that Yahoo knew more about the case than it claimed in testimony given last year. U.S. lawmakers have been querying Yahoo about its business practices in China for the past couple years. Last year, Callahan said that Yahoo had no information about the Chinese government's wishes for customer information. Lo and behold, it turns out Yahoo was in possession of an order from Beijing seeking information about Shi. Callahan's apology comes in advance of another Congressional hearing next week about the challenges and moral quandaries that U.S. companies like Yahoo face in doing business in authoritarian places such as China. It's great that Yahoo is starting to come clean, but that's undoubtedly little comfort to Shi Tao, who still has at least another seven years to go in prison.
