Analysis: We could see more protests in other American cities
We could see more protests on the streets of other American cities as Donald Trump's immigration policies continue to be acted out, our US correspondent Mark Stone reports.
Stone says there is no evidence at this stage that the LA protesters were paid to protest.
"The focus of the protests - to which maybe some hardliner leftists have joined - has been Trump's immigration policies," he says.
Looking at Trump's mention of the Insurrection Act, Stone explains this would allow him to deploy the military, which he appears already to have done, but in a more "forceful way" and probably through the courts.
"That's if he can prove that what we are seeing is an insurrection. He didn't clarify how he would prove that," Stone says.
"What he and his homeland security chief said, is that they will continue to deploy the National Guard and perhaps the Marines as well.
"And they will do it in other states if necessary.
"I think we could be in for perhaps a summer of seeing this sort of thing on the streets of other American cities as Trump's immigration reforms and policies continue to be acted out."
