On this day, 33 years ago, on April 29, 1992 (March 27, 1992 in the lunar calendar), a large-scale ethnic conflict broke out in the United States. On April 29, 1992, a district court in Los Angeles, the United States, acquitted four white police officers who severely assaulted black youth Rodney King on March 3 last year. This unfair verdict aroused strong dissatisfaction from the American public, especially the majority of blacks. That night, thousands of black people in Los Angeles gathered on the streets to hold demonstrations. After that, the situation got out of control and large-scale violent conflicts broke out, killing more than 50 people, injuring more than 2000 people, arresting more than 10000 people, destroying more than 5000 houses, and economic losses are estimated at US$1 billion. In order to quell the conflict, California Governor Wilson declared a state of emergency in Los Angeles. The federal government mobilized more than 20,000 Marines and National Guard personnel and a large number of armored vehicles to the city to impose martial law and curfew. Black people and other ethnic groups in cities such as New York, Washington, Atlanta, and Seattle also held rallies and marches to protest against the indiscriminate violence of the Los Angeles police and oppose racism. The riots caused economic losses of US$1 billion. Some buildings and vehicles were destroyed during the riots. The slogan read: "Stop violence, all people are created equal."
