Los Angeles residents and experts say that the National Guard's presence in Los Angeles in response to immigration protests is reminiscent of a longstanding dynamic in the state and around the country.

LOS ANGELES (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.

U.S. officials said about 1,000 National Guard members were in the city under federal orders by midday Monday.
