Missing booksellers: Hong Kong protests

Thousands of Hong Kongers took to the city's streets Sunday to protest the mysterious disappearance of a number of publishers and booksellers. The protesters say five citizens -- some of whom also hold European passports and who publish books that are often critical of the Chinese leadership -- were taken by Chinese authorities. In mainland China the government places strict controls on mass media, which often means that political analysis and controversial accounts of Chinese history are impossible to find within the country's borders. However, bookstores in Hong Kong -- a special administrative region of China that has freedom of press -- are cashing in on the ban to cater to the millions of mainland Chinese who travel to Hong Kong to shop. Bookstores stock their shelves with forbidden tales of everything from the Tiananmen Square crackdown of 1989 to the scandal of ousted Communist Party official Bo Xilai.
