Mountain View’s decision to shut down its automated license plate reader program is a reminder of an uncomfortable truth that surveillance technology is only as trustworthy as the systems—and vendors—behind it.
This week, Police Chief Mike Canfield announced that all Flock Safety ALPR cameras in Mountain View have been turned off, effective immediately. The move pauses the city’s pilot program until the City Council reviews its future at a February 24 meeting.
The decision comes after the police department discovered that hundreds of unauthorized law enforcement agencies had been able to search Mountain View’s license plate camera data for more than a year—without the city’s awareness.
For a tool that was sold to the public as tightly controlled and privacy-focused, this is a serious breach of trust.
Flock Safety ALPR Cameras Shut Down Over Data Access Failures
In his message to the community, Chief Canfield made it clear that while the Flock Safety ALPR pilot program had shown value in solving crimes, he no longer has confidence in the vendor.
“I personally no longer have confidence in this particular vendor,” Canfield wrote, citing failures in transparency and access control.
The most troubling issue, according to the police chief, was the discovery that out-of-state agencies had been able to search Mountain View’s license plate data—something that should never have been possible under state law or city policy.
This wasn’t a minor technical glitch. It was a breakdown in oversight, accountability, and vendor responsibility.
Automated License Plate Readers Under Growing National Scrutiny
Automatic license plate readers, or ALPR surveillance cameras, have become one of the most controversial policing technologies in the United States.
These cameras capture images of passing vehicles, including license plate numbers, make, and model. The information is stored and cross-checked with databases to flag stolen cars or vehicles tied to investigations.
Supporters argue that ALPRs help law enforcement respond faster and solve crimes more efficiently.
But critics have long warned that ALPR systems can easily become tools of mass surveillance—especially when data-sharing controls are weak.
That concern has intensified under the Trump administration, as reports have emerged of license plate cameras being used for immigration enforcement and even reproductive healthcare-related investigations.
Mountain View’s case shows exactly why the debate isn’t going away.
Mountain View Police Violated Its Own ALPR Policies
According to disclosures made this week, the Mountain View Police Department unintentionally violated its own policies by allowing statewide and national access to its ALPR data.
Chief Canfield admitted that “statewide lookup” had been enabled since the program began 17 months ago, meaning agencies across California could search Mountain View’s license plate records without prior authorization.
Even more alarming, “national lookup” was reportedly turned on for three months in 2024, allowing agencies across the country to access the city’s data.
State law prohibits sharing ALPR information with out-of-state agencies, especially for immigration enforcement purposes.
So how did it happen?
Canfield was blunt: “Why wasn’t it caught sooner? I couldn’t tell you.”
That answer won’t reassure residents who were promised strict safeguards.
Community Trust Matters More Than Surveillance Tools
Chief Canfield’s message repeatedly emphasized one point: technology cannot replace trust.
“Community trust is more important than any individual tool,” he wrote.
That statement deserves attention. Police departments across the country have adopted surveillance systems with the promise of safety, only to discover later that the systems operate with far less control than advertised.
When a vendor fails to disclose access loopholes—or when law enforcement fails to detect them—the public pays the price.
Canfield acknowledged residents’ anger and frustration, offering an apology and stating that transparency is essential for community policing.
It’s a rare moment of accountability in a space where surveillance expansion often happens quietly.
Flock Safety Faces Questions About Transparency and Oversight
Mountain View’s ALPR program began in May 2024, when the City Council approved a contract with Flock Safety, a surveillance technology company.
Since August 2024, the city installed cameras at major entry and exit points. By January 2026, Mountain View had 30 Flock cameras operating.
Now, the entire program is paused.
Flock spokesperson Paris Lewbel said the company would address the concerns directly with the police chief, but the damage may already be done.
This incident raises a bigger question: should private companies be trusted to manage sensitive surveillance infrastructure in the first place?
What Happens Next for the Flock Safety ALPR Program?
The City Council will now decide whether Mountain View continues with the Flock contract, modifies the program, or shuts it down permanently.
But the broader lesson is already clear.
ALPR surveillance cameras may offer law enforcement real investigative value, but without airtight safeguards, they risk becoming tools of unchecked monitoring.
Mountain View’s shutdown is not just a local story—it’s part of a national reckoning over how much surveillance is too much, and whether public safety can ever justify the loss of privacy without full accountability.
