HONG KONG -- Hong Kong's national security law had just taken effect last June when the city's film censors examined "Inside the Red Brick Wall" -- a documentary about the siege of Hong Kong Polytechnic University during the 2019 protests.
The officials gave the film a green light, though it could only be shown to audiences aged 18 and above. A disclaimer was added at the authorities' request, emphasizing that some of the acts documented "may constitute criminal offenses under prevailing laws."
