Four protesters filed a lawsuit against the Department of Homeland Security (DHS) and the Federal Bureau of Investigation (FBI) in an Illinois district court, aiming to halt the collection of DNA samples from individuals arrested during peaceful protests against Immigration and Customs Enforcement (ICE) activities. The complaint, lodged on Wednesday, asserts that the federal government wrongfully arrested demonstrators and unlawfully seized their DNA, which was subsequently stored in government databases. Among the 92 non-immigration arrests at the Broadview ICE facility during 'Operation Midway Blitz,' only one protester faced a conviction, which was unrelated to the protest itself. The plaintiffs argue that federal officials have overstepped their authority and that the Supreme Court's 2013 ruling allows DNA collection only under specific circumstances—namely, valid arrests for serious offenses confirmed by a judicial officer. They emphasize that any collected DNA should be used solely for identification, not for extracting information about relatives or health.
