Immigration Enforcement Tools Repurposed for Domestic Surveillance

Background and Scope of the Surveillance System
Since 2008 ICE has built a data-driven enforcement system originally meant to locate undocumented migrants. A 2022 Georgetown Law Center study found ICE had scanned driver-license photos of one-third of adults, accessed license data of three-quarters, and could locate three-quarters via utility records. Between 2008 and 2021 the agency spent roughly $2.8 billion on surveillance, data-collection and data-sharing, including a Palantir contract for near-real-time tracking. The network now lets thousands of agents query information on over 300 million people, including U.S. citizens, using tools such as the ELITE phone app and the Mobile Fortify facial-recognition platform.
Official Agency Statements
The Department of Homeland Security says agents use the Mobile Fortify app on government-issued devices to photograph individuals; the image is sent to CBP’s Traveler Verification Service and stored for fifteen years. ICE also uses the Penlink system, which lets agents geofence an area and identify all cell phones within range, according to Vanderbilt Law School researcher Bianca Castillo.
Criticism from Civil-Liberties Groups
Civil-rights groups say repurposing immigration tools threatens constitutional rights. EPIC warns that “ICE is currently using the Mobile Fortify app in the field to identify anyone they happen to encounter and want to identify.” FIRE notes officials “don’t enjoy special immunity from ‘doxxing,’” and Freedom Forum reminds courts protect the right to record law-enforcement in public. Scholars cite the Carpenter decision, which requires a warrant for mobile-phone location data, as a possible violation of Penlink’s warrantless use.
On-the-Ground Example
In Maine, resident Liz McLellan photographed federal agents during an immigration raid. Agents later visited her home and said, “This is a warning. We know you live right here.” The incident illustrates how tools built for border enforcement are applied to U.S. citizens exercising protected speech.
Conflicting Reports & Gaps
The sources do not provide independent data on how frequently Mobile Fortify or Penlink are used against U.S. citizens, nor do they detail legal standards governing the fifteen-year retention of biometric records. This lack of transparency hampers assessment of compliance with Fourth-Amendment requirements.

What’s Next
Civil-rights groups are urging congressional oversight and judicial review of ICE’s surveillance contracts. Pending lawsuits may challenge the warrantless use of Penlink and the long-term storage of biometric data, potentially reshaping the legal framework for domestic surveillance.
