how about a private company (TLO) recording >2B vehicle license plate sightings (and adding >50M per year?

http://www.tlo.com/vehicle-sightings

this company also built a system for peer-to-peer traffic surveillance (looking for child porn) until TransUnion 
acquired TLO and spun that off to a not-for-profit...

Oh, great!  Another layer of privacy protection eliminated.  Next step is to monetize the results -- I've already 
heard of town councils saying they want to use the data to identify drivers who go through their town regularly so 
they can target them with ads for local businesses.

Why aren't we demanding immediate (24-hour?) deletion of all public surveillance information that is not needed for 
a specific investigation.  That's the only way it won't be abused.  Plus, if it's needed for a specific 
investigation, there should be a warrant showing why it's needed.

Electronic Frontier Foundation, ACLU Win Court Ruling That Police Can't Keep License Plate Data Secret
Police Have Collected Data on Millions of Law-Abiding Drivers Via License Readers

SAN FRANCISCO, CALIFORNIA—The Electronic Frontier Foundation (EFF) and the ACLU won a decision by the California 
Supreme Court that the license plate data of millions of law-abiding drivers, collected indiscriminately by 
police across the state, are not “investigative records” that law enforcement can keep secret. 

California’s highest court ruled that the collection of license plate data isn’t targeted at any particular 
crime, so the records couldn’t be considered part of a police investigation. 

“This is a big win for transparency in California,” attorney Peter Bibring, director of police practices at the 
ACLU of Southern California, which joined EFF in a lawsuit over the records.  “The California Supreme Court 
recognized that California’s sweeping public records exemption for police investigations doesn’t cover mass 
collection of data by police, like the automated scanning of license plates in this case. The court also 
recognized that mere speculation by police on the harms that might result from releasing information can’t defeat 
the public’s strong interest in understanding how police surveillance impacts privacy."

The ruling sets a precedent that mass, indiscriminate data collection by the police can’t be withheld just 
because the information may contain some criminal data. This is important because police are increasingly using 
technology tools to surveil and collect data on citizens, whether it’s via body cameras, facial recognition 
cameras, or license plate readers.

The panel sent the case back to the trial court to determine whether the data can be made public in a redacted or 
anonymized form so drivers’ privacy is protected.

“The court recognized the huge privacy implications of this data collection,” said EFF Senior Staff Attorney 
Jennifer Lynch. “Location data like this, that’s collected on innocent drivers, reveals sensitive information 
about where they have been and when, whether that’s their home, their doctor’s office, or their house of worship.”

Automated License Plate Readers or ALPRs are high-speed cameras mounted on light poles and police cars that 
continuously scan the plates of every passing car. They collect not only the license plate number but also the 
time, date, and location of each plate scanned, along with a photograph of the vehicle and sometimes its 
occupants. The Los Angeles Police Department (LAPD) and the Los Angeles County Sheriff's Department (LASD) 
collect, on average, three million plate scans every week and have amassed a database of half a billion records.

EFF filed public records requests for a week’s worth of ALPR data from the agencies and, along with American 
Civil Liberties Union-SoCal, sued after both agencies refused to release the records.

EFF and ACLU SoCal asked the state supreme court to overturn a lower court ruling in the case that said all 
license plate data—collected indiscriminately and without suspicion that the vehicle or driver was involved in a 
crime—could be withheld from disclosure as “records of law enforcement investigations.”

EFF and the ACLU SoCal argued the ruling was tantamount to saying all drivers in Los Angeles are under criminal 
investigation at all times. The ruling would also have set a dangerous precedent, allowing law enforcement 
agencies to withhold from the public all kinds of information gathered on innocent Californians merely by 
claiming it was collected for investigative purposes.

EFF and ACLU SoCal will continue fighting for transparency and privacy as the trial court considers how to 
provide public access to the records so this highly intrusive data collection can be scrutinized and better 
understood.
