LOS ANGELES—Riots in protest of federal immigration operations, prompting President Donald Trump to deploy troops into Los Angeles, have precipitated a showdown between state and federal power.
Over the weekend, violence erupted as protestors broke off pieces of cinder blocks and cement structures to throw at law enforcement vehicles. They also tossed scooters and debris from freeway overpasses onto police cruisers, set vehicles ablaze, set off fireworks aimed at officers, and blocked roads.
