ACLU v. CBP - FOIA Case for CBP and ICE Records Related to the Use of Cell-Site Simulator TechnologyACLU v. CBP - FOIA Case for CBP and ICE Records Related to the Use of Cell-Site Simulator Technology
On May 19, 2017, ACLU submitted a FOIA request to U.S. Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP) demanding records on the federal government's acquisition and use of "cell site simulators" (also known as "Stingrays" or "IMSI catchers"), powerful surveillance devices that target cell phones by impersonating a wireless service provider's cell tower. For more than two years, the two agencies failed to properly process the Request or produce any responsive records until the ACLU sued on December 11, 2019.
