Homeland Security hopes to build a national database based on information gathered from license-plate readers, the Washington Post reports.
The idea is to help locate and arrest “absconders and criminal aliens” while also reducing surveillance hours.
DHS spokesman Gillian Christensen emphasized that the database would “only be accessed in conjunction with ongoing criminal investigations.”
License-plate readers automatically records vehicles.
The ACLU claims the devices are an invasion of privacy.
“More and more cameras, longer retention periods, and widespread sharing allow law enforcement agents to assemble the individual puzzle pieces of where we have been over time into a single, high-resolution image of our lives,” the ACLU said.
