President-elect Donald Trump will return to power next year with a raft of technological tools at his disposal that would help deliver his campaign promise of cracking down on immigration — among them, surveillance and artificial intelligence technology that the Biden administration already uses to help make crucial decisions in tracking, detaining and ultimately deporting immigrants lacking permanent legal status. While immigration officials have used the tech for years, an October letter from the Department of Homeland Security obtained exclusively by The Associated Press details how those tools — some of them powered by AI — help make decisions over whether an immigrant should be detained or surveilled. One algorithm, for example, ranks immigrants with a “Hurricane Score,” ranging from 1-5, to assess whether someone will “abscond” from the agency’s supervision. The letter, sent by DHS Chief Artificial Intelligence Officer Eric Hysen to the immigrant rights group Just Futures Law, revealed that the score calculates the potential risk that an immigrant — with a pending case — will fail to check in with Immigration and Customs Enforcement officers.
