A federal judge in Chicago is pressing immigration officials, including ICE and Border Patrol, for answers regarding their recent operations and the controversial use of tear gas during immigration enforcement actions. The judge has ordered federal agents to wear body cameras to ensure accountability amid rising tensions and public clashes during these operations. Officials are expected to testify in court about their tactics, with some defending their use of aggressive measures as a response to perceived dangers during their operations. Concerns have been raised about the implications of these tactics, with demands for more oversight and potential changes to procedures. The order for body cameras is seen as a significant step towards ensuring transparency in the enforcement activities taking place in the city.
