From AP:
Tensions in Los Angeles escalated Sunday as thousands of protesters took to the streets in response to President Donald Trump’s extraordinary deployment of the National Guard, blocking off a major freeway and setting self-driving cars on fire as law enforcement used tear gas, rubber bullets, and flash bangs to control the crowd.
Some police patrolled the streets on horseback while others with riot gear lined up behind Guard troops deployed to protect federal facilities including a detention center where some immigrants were taken in recent days. Police declared an unlawful assembly, and by early evening many people had left.
