Immigration detention is not a criminal procedure. And yet the Trump administration is treating it as a criminal punishment. It is using detention to inflict pain on anyone — immigrant or citizen — caught in its grasp. It is subjecting detainees to horrific conditions of deprivation and abuse, meant to pressure people into leaving the country, even if they have valid asylum claims or even legal status. And the administration is trying to expand its system of internment camps, purchasing warehouses across the country meant to hold tens of thousands of people — an archipelago custom-ordered by America’s most famous real estate developer, Donald Trump.
