Hong Kong Police Disperse Protesters Opposing National Security, Anthem Laws Verna Yu HONG KONG - Riot police in Hong Kong Wednesday fired pepper balls to disperse tens of thousands of demonstrators protesting adoption of a controversial national security law that is poised to pass in Beijing on Thursday and a proposed law criminalizing the disrespect of the national anthem tabled in the city's legislature. Thousands of riot police officers guarded several districts in Hong Kong, firing pepper balls and using pepper spray to disperse protesters. Police stopped and searched mostly young people outside subway stations and on the streets throughout the day. Crowds of people who gathered in Admiralty, the area where the legislative council and government quarters are located, were dispersed by police who threatened them with pepper spray if they did not comply. There were police officers guarding every street corner in the area to prevent people from getting near the government buildings. Walkways leading to the government buildings were cordoned off. Police quickly closed in on small groups of activists who gathered to chant slogans and give speeches expressing their opposition to the national anthem bill. At one point, police ordered people in nearby restaurants to leave. WATCH: Street view of Hong Kong protesters .
