Demonstrators march through Little Tokyo and toward L.A. City Hall on Jan. 23, a day activists called an “economic blackout,” urging Americans to avoid work, school and shopping, to voice ire and anger against the Trump administration’s immigration enforcement tactics. The protest was one of many in cities across the nation, and came a day before the second killing of a protestor by federal agents in Minneapolis this month. The death of nurse Alex Pretti came amid what immigration officials have called expanded enforcement that has made the Twin Cities a flashpoint over the administration’s policies.
