Protests activists Minnesota Immigration Enforcement ICE.

If there’s been a soundtrack to life in Minneapolis in recent weeks, it’s the shrieking whistles and honking horns of thousands of people following immigration agents across the city. They are the ever-moving shadow of Operation Metro Surge. They are teachers, scientists and stay-at-home parents. They own small businesses and wait tables. And when the White House shifted to a more conciliatory tone after the weekend killing of Alex Pretti, holding talks with local and state that President Donald Trump had long disdained and pushing aside Gregory Bovino, the Border Patrol senior official who had become public face of the immigration crackdown, it was quickly clear no one was giving up.
