Legislative Council president Tsang Yok-sing is to lead a delegation to visit Shanghai next weekend. Legislators are to have a half day meeting with Wang Guangya, the Director of the Hong Kong and Macau Affairs Office of the state council, Li Fei, the Chairman of the Hong Kong Special Administrative Region Basic Law Committee and Zhang Xiaoming, the Director of the Liaison Office The topic they want to discuss is Hong Kong's political development. Democrats are split on whether or not to take part. On Wednesday this week, Bill Majcher, a former covert operative for the Canadian government, gave a speech at the Foreign Correspondents' Club on how and why public safety has been compromised by allegedly reckless disclosures by digital anarchists masquerading as whistleblowers. That is contentious stuff. Well, Bill Majcher is in the studio with us now. Last week, mainland Chinese dissident Tan Zuoren was released from prison after a five year jail term. Tan was arrested on March 28, 2009 on charges of "inciting subversion of state power" because of essays he'd published criticizing the government verdict on the crackdown against the 1989 Tiananmen protests. But his supporters however believe he was targeted because of his investigations into the collapse of school buildings during the 2008 Sichuan earthquake.
