A suite of new laws restricting cooperation between Maine law enforcement and Department of Homeland Security agents is set to take effect today, less than three weeks after an ICE agent shot and killed 25-year-old Johan Sebastián Durán Guerrero in Biddeford, Maine. These “ICE Out laws,” as they’re collectively known, will limit collaboration between state and local police and federal agents, and forbid landlords, hospitals, and schools from sharing personal information with ICE. These are outgrowths of the “sanctuary city” and “sanctuary state” laws of the first Trump term, which generally limited local police partnerships with ICE. But at least eight states have passed laws mandating local agency cooperation with ICE, instead. Because ICE is a federal agency, Maine cannot fully bar it from operating in the state—but there are some things states can do to restrict the agency’s movement.
