ICE agents are using facial recognition, DNA collection, and location tracking against American citizens and lawful residents during immigration enforcement operations. NPR reporters document how protesters and legal observers in Minneapolis faced body slams, DNA swabs, home surveillance, and online subpoenas for exercising first amendment rights. ICE collected DNA samples from at least six people in Minnesota, Illinois, Oregon, and California who were lawfully protesting or observing federal immigration operations, with no clarity on where samples are stored or how they're used.
