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.

The Pentagon on Monday ordered a battalion of 700 Marines to Los Angeles and mobilized an additional 2,000 National Guard troops as protests of the Trump administration’s immigration policies spilled into a fourth day,

The deployment was unauthorized by Gov. Gavin Newsom, who wrote that federal actions inflamed tensions while pulling away resources.
