MINNEAPOLIS (AP) — 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. Their network is sprawling, often anonymous and with few overall objectives beyond helping immigrants, warning of approaching agents or filming videos to show the world what is happening. At least 2,000 ICE officers and 1,000 Border patrols officers were on the ground. They smashed through the front door of a Liberian man and detained him without a proper warrant, even though he'd been checking in regularly with immigration officials. Protester caravans regularly form behind immigration convoys, creating mobile protests of anger and warning that weave through city streets.
