Dissidents to ground

Chinese activist and artist Ai Weiwei waves to journalists before entering the Beijing No. 2 People's Intermediate Court for an appeal in Beijing, Sept. 27, 2012.

Hundreds of activists and dissidents are under house arrest for the duration of the Congress. Ai, who is normally happy to speak to media, was reluctant to speak to CBS News in the run-up to the Congress.
