Protests in Los Angeles against Immigration and Customs Enforcement raids entered their fourth day as police fired on demonstrators. Thousands blocked a major freeway and set cars on fire, prompting law enforcement to use tear gas and rubber bullets. California sued the Trump administration over unauthorized National Guard deployment. By Monday afternoon, 53 arrests were made, including charges of assault, looting, and arson. Authorities from multiple agencies are involved in controlling the unrest and making arrests.
