In November 2019, some one thousand young pro-democracy protesters occupied the campus of Hong Kong’s Polytechnic University, which is located at a crucial junction of two highways and the cross-harbor tunnel. They disrupted traffic for more than a week, trying to pressure the government to investigate police misconduct during large-scale protests earlier in the year. On November 17, they repulsed police efforts to storm the campus. The police threatened to use live ammunition but decided to starve them out instead.
