Surveillan­ce cameras embraced despite concerns

Police report license plate readers have helped reduce crime, but others say they're an invasion of privacy

Every time someone drives in or out of Morgan Hill, an automated camera takes a swift snapshot of the license plate. A web of 50 cameras form a virtual net around the city and their use has been accompanie­d by a string of arrests and a marked drop in some property crimes, according to the South Bay city's police department.

Morgan Hill was among the first cities in the Bay Area to adopt such a complex network of license plate readers and — according to statistics provided by the police department — it's among the most successful. But as the technology is set to spread through the region, privacy experts worry that the cameras also function as a surveillan­ce system hiding in plain sight, even as the threat they pose goes under the radar.

The police department's interest in the license plate readers began in 2020 after a suspect fired fatal shots from one vehicle into another. When the department couldn't immediatel­y find the shooter, they began looking for tools that would help them track down vehicles associated with crime.

They settled on automated license plate readers that take a snapshot of a moving car, garnering informatio­n about the license plate number as well as the make, model and color. If the license plate matches that of a stolen car or a vehicle associated with a crime or Amber Alert, the department is automatica­lly notified. After verifying the alert, it can take action.

In August 2021, the department started with 25 cameras as a pilot program. It expanded to a stock of 50 covering the city's entrances and exits, as well as the main roads.

Together with maintenanc­e and data storage, the cameras cost $120,000 each year to maintain and are run by a Georgia company, Flock Safety.

Two years into the program, the police department is declaring the cameras a success. Police say the cameras have enabled more than 200 arrests in connection with nearly 700 criminal offenses, meaning that most arrests were connected to multiple crimes, including carjacking­s and homicides.

“It's an amazing tool,” police spokespers­on Scott Purvis said. “The numbers speak for themselves.”

Additional­ly, the department claims that monthly averages for property crimes dropped significan­tly. Burglaries dropped from an average of about 10 a month in the two years preceding the use of the cameras to just more than six a month in the subsequent two years — a 36% decrease, police said.

Larcenies, simple thefts that don't involve an additional element, dropped by 14%, from

about 42 per month to about 36, on average. They also say catalytic converter thefts dropped 66%.

When this news organizati­on requested the monthly data backing up these figures, however, the department said it could not provide them.

“We are in the process of transition­ing to a new records management system … and hope to be able to publish these reports in the very near future,” the department said in an email.

The network of cameras is meant to give investigat­ors a clear idea of the path that a car associated with a crime takes through the city, but privacy concerns have arisen over the fact that the system captures and stores the data of all passing vehicles, regardless of whether they are associated with a crime.

According to a 2014 report by the Rand Corp., a public policy research organizati­on, this data could allow “authoritie­s to reconstruc­t individual­s' movements across space and time.”

Other privacy rights groups and community members worry about what they see as overreach, such as using the cameras for immigratio­n enforcemen­t or to investigat­e minor infraction­s such as speeding.

Many Morgan Hill residents are unaware of the system, bolstering the concerns of some privacy experts.

“All the data are being gathered without our consent,” said Roxana Marachi, who researches surveillan­ce technology and formerly served on the San Jose Digital Privacy Advisory Task Force that reviewed license plate cameras. “The average person does not know.”

However, many residents said they were supportive of the new crime-fighting tool despite those concerns.

“I think it's good” for solving crimes, Morgan Hill resident Norma Martinez said, “How far will it go? That's the issue.”

While acknowledg­ing that “there will always be a tradeoff between security and privacy,” Mashieka Allgood, an AI expert who fought against the implementa­tion of license plate cameras in San Jose, saidin an email that the expansion of license plate readers poses a “significan­t risk” and is a potential violation of the Fourth Amendment, which protects against unreasonab­le search.

The police department and tech provider Flock have taken steps to dispel some of the Orwellian fears of mass surveillan­ce. Flock sets a maximum storage time of 30 days for data, after which it is permanentl­y deleted unless it is being used as evidence in a case.

Each time an officer accesses the data, they must submit their badge number and a reason for accessing the data. The record of their search is stored indefinite­ly. According to Flock, this discourage­s misuse of the system.

Additional­ly, the California Values Act offers protection from police department­s sharing data with immigratio­n enforcemen­t. Purvis said the technology cannot be used for traffic enforcemen­t.

In a 2022 report on Flock's license plate readers, the American Civil Liberties Union described the data protection measures as “necessary but not sufficient” and gave a series of recommenda­tions for making the system less invasive. Chief among these suggestion­s was quickly deleting license plate images that did not result in a hit on a hotlist, perhaps after just a few minutes.

Regardless of the concerns, the tool seems to be spreading across the Bay Area. License plate readers are in use in San Jose, Vallejo, Campbell and Fremont, among others. Other cities, such as Oakland, are considerin­g expanding their use of the system.

While residents of Morgan Hill may weigh safety over privacy concerns, others elsewhere in the Bay Area may come to a different conclusion.

“What's the cost of being monitored and our community being monitored and feeling like you're being watched?” asked TJ McKillop, a Sonoma County resident visiting Morgan Hill.
