On November 14, about a hundred thousand of citizens including members of 53 organizations such as the Korean Confederation of Trade Unions joined together in the massive demonstration in downtown Seoul to protest against the government’s decision to require secondary schools to use the state-authored Korean history textbook, as well as against problems of poverty, farming issues, and other controversial issues. The police attempted to control the protesters by employing 700 buses and 20 roadblocks and closing Gyeongbokgung Station and Gwanghwamun Station. Also, to a growing number of protesters, the police used water cannons that contains capsaicin. They deliberately aimed at the heads of protesters, not their bodies. In one case, protesters claimed that the police had shot their water cannon at a demonstrator who was being taken in an ambulance. Also in another incident, a 69-year-old demonstrator collapsed after being hit by a water cannon, resulting in a concussion after he lost consciousness.
