Xinhua News Agency, Los Angeles, May 30 (Reporter Takayama) On the 29th, Los Angeles, the largest city in the western United States, staged a demonstration for the third day in a row to protest against the police’s violent law enforcement, which turned into riots. Local police said that 533 people had been arrested by the morning of the 30th.
Hundreds of demonstrators gathered in downtown Los Angeles on the evening of the 29th, shouting slogans such as "We can’t breathe" to protest against the brutal law enforcement by white police in Minneapolis, Minnesota, which killed the African-American man George Floyd. Some demonstrators briefly blocked a major highway through the city.

Before midnight, the demonstration gradually got out of control and the protesters clashed with the police. The TV screen shows that the window of some shops along the street was smashed, and some people took the opportunity to enter the smashed jewelry stores, supermarkets and other looting items. At least one police car burst into flames after being set on fire.
According to local media reports, the police fired tear gas at the crowd and once used rubber bullets to disperse the crowd. The police declared the crowd an "illegal gathering" and arrested those who refused to obey orders and left the street. This is the largest arrest by LAPD in the last decade.
Los Angeles police said that six police officers were injured in the conflict. The police said they would send more police to deal with more demonstrations that may occur.
Los Angeles Police Commissioner Michelle Moore wrote on social media on the 30 th: "Last night was a heavy warning of the dangers brought by social unrest."
According to the video on social media, a white policeman held Freud’s neck tightly with his knee for a long time during law enforcement on the 25th. Freud looked miserable and hoarse, and kept saying that he couldn’t breathe. Then he was suspected of falling into a coma and died after being sent to the hospital. This incident has caused public outcry in the United States and triggered protests in several cities in the past few days.
