United States immigration authorities are planning to secure long-term detention and transportation capacity for Immigration and Customs Enforcement operations across Minnesota and four neighboring states, according to an internal planning document reviewed by WIRED. The deployment has sparked repeated protests in Minneapolis and Saint Paul, including marches to downtown hotels where demonstrators said federal agents were staying, and confrontations that have drawn arrests and widespread use of tear gas and chemical irritants. In court, a federal judge set restrictions on federal agents participating in Metro Surge from using force against peaceful protesters and observers. Those records outlined a nationwide expansion of detention capacity and a move to mega-facilities that can house a thousand people or more. Appleton city administrator John Olinger tells WIRED he has had no contact with ICE or CoreCivic since the matter came up last fall.
