Palantir is working on a tool for Immigration and Customs Enforcement (ICE) that helps identify potential deportation targets and their locations. The tool uses data from various sources, including the Department of Health and Human Services, to populate a map and provide a confidence score on the person's current address. ICE is using this tool to find locations where large numbers of people could be detained. This technology is being used in conjunction with increased ICE presence in areas like Minneapolis, where protests against the agency are ongoing.
