Work starts around sunrise for the federal officers carrying out the immigration crackdown in and around the Twin Cities, with people in tactical gear streaming from a bland office building. Soon they leave in the unmarked convoys which have quickly become feared and common sights in the streets of Minneapolis, St. Paul and their suburbs. Operation Metro Surge is the Trump administration’s latest and biggest crackdown yet, with more than 2,000 officers taking part. It has pitted local officials against the federal government, sparked daily clashes between activists and immigration officers, and left a mother of three dead. The crackdown is barely noticeable in some areas, but it can be felt across broad swaths of the Twin Cities area.
