U.S. Immigration and Customs Enforcement (ICE) has been employing a clandestine strategy to track migrants using cellular location data. The agency utilizes fake cell towers, known as “cell-site simulators” or “stingrays,” to pinpoint the locations of individuals. Reports indicate that established protocols regarding warrant requirements and data retention may not have been consistently followed during these operations. This practice raises significant privacy concerns, as it potentially captures data from individuals who are not targets of investigation. Details of the strategy and alleged protocol breaches have recently come to light, prompting scrutiny of ICE’s surveillance tactics. Civil liberties advocates are questioning the legality and ethical implications of the program, emphasizing the broad scope of data collection. The extent and duration of this tracking operation remain under investigation.
