ICE spent $825K this year on vehicles with IMSI catchers

In a contract worth $825,000, the U.S. Immigration and Customs Enforcement (ICE) acquired surveillance vehicles equipped with cell-site simulators, also known as IMSI catchers, this year. These devices can intercept mobile phone signals and track users' locations without obtaining a warrant, raising privacy concerns. The article also notes ICE's recent controversies, such as unlawfully detaining U.S. citizens and using violence against journalists and protesters, as it carries out the immigration enforcement ordered by President Donald Trump. The passive versions of IMSI catchers are less intrusive, but the active ones can intercept all data transferred from mobile phones and track their locations, potentially interfering with users' ability to contact emergency services.
