Documents Show Location Records Being Kept on Innocent Nebraskans

LINCOLN - Police departments around the country, including in Nebraska, are rapidly expanding their use of automatic license plate readers to track the location of American drivers, but few have meaningful rules in place to protect drivers' privacy rights, according to documents released today by the American Civil Liberties Union. As a result, the new documents reveal, many departments are keeping innocent people's location information stored for years or even indefinitely, regardless of whether there is any suspicion of a crime.

"The spread of these scanners is creating what are, in effect, government location tracking systems recording the movements of many millions of innocent Americans in huge databases," said ACLU Staff Attorney Catherine Crump, the report's lead author. "We don't object to the use of these systems to flag cars that are stolen or belong to fugitives, but these documents show a dire need for rules to make sure that this technology isn't used for unbridled government surveillance."

The systems use cameras mounted on patrol cars or on objects like road signs and bridges, and the documents show that their deployment is increasing rapidly, with significant funding coming from federal grants. They photograph every license plate they encounter, use software to read the number and add a time and location stamp, then record the information in a database. Police are alerted when numbers match lists containing license numbers of interest, such as stolen cars.

Last summer, ACLU of Nebraska along with affiliates in 37 other states and Washington filed nearly 600 freedom of information requests asking federal, state, and local agencies how they use the readers. The 26,000 pages of documents produced by the agencies that responded _ about half _ include training materials, internal memos, and policy statements. The results and analysis are detailed in an ACLU report released today called "You Are Being Tracked," which includes charts and policy recommendations.

The study found that not only are license plate scanners widely deployed, but few police departments place any substantial restrictions on how they can be used. Omaha and Lincoln Police Departments have used license plate readers but have no formal writen policies associated with their use. Records show that the OPD database still has photographs from 2009. While many police departments do prohibit police officers from using license plate readers for personal uses such as tracking friends, these are the only restrictions.

A tiny fraction of the license plate scans are flagged as "hits." For example, the Nebraska State Patrol scanned almost 7,000 plates during a one-month period of time in 2008. This lead to 14 hits (.002%) all of which were eventually rejected.

"The fact that some jurisdictions delete the records quickly shows that it is a completely reasonable and workable policy. We need to see more laws and policies in place that let police protect both public safety and privacy," said Becki Brenner, ACLU of Nebraska Executive Director. "The police should not be storing data about people who are not even suspected of doing anything wrong. Targeting everyone at a so-called 'gang funeral' as one Nebraska agency did shows the clear overreach possible when this technology is used without proper oversight."

The ACLU report released today has over a dozen specific recommendations for government use of license plate scanner systems, including: police must have reasonable suspicion that a crime has occurred before examining the data; unless there are legitimate reasons to retain records, they should be deleted within days or weeks at most; and, people should be able to find out if their cars' location history is in a law enforcement database.

License plate readers are used not only by police but also by private companies, which themselves make their data available to police with little or no oversight or privacy protections. One of these private databases, run by a company called Vigilant Solutions, holds over 800 million license plate location records and is used by over 2,200 law enforcement agencies, including the U.S. Department of Homeland Security.

"Police departments should not use databases that do not have adequate private protections in place," said Amy Miller, ACLU of Nebraska Legal Director.
