Oakland Woman Pulled Over After Thieves Swapped Her License Plates

Ann Nomura was driving through Hayward earlier this month when police lights appeared in her rearview mirror. The 65-year-old Oakland resident pulled over, not knowing what to expect. What followed shook her: officers ordered her out of the car with her hands up, treating her as a suspect connected to a serious crime.

She had done nothing wrong.

What Nomura didn’t know was that someone had swapped her license plates with stolen plates tied to a criminal incident. A Flock license plate reader had scanned her car and flagged it for law enforcement. By the time officers figured out she had no connection to the case, the damage was already done.

“That is when it sort of hit me that I was being treated as a potential criminal and could have been hurt,” Nomura said, speaking to the Oaklandside.

The tactic used to set her up is known as “cold-plating.” Thieves remove plates from one vehicle and place them on another, allowing them to move through neighborhoods, toll plazas, and now speed camera zones without detection. The technique has been used to mask involvement in break-ins, robberies, and toll evasion. According to KGO, the spread of speed cameras has pushed more thieves toward the practice as a way to dodge automated enforcement.

Sgt. Roberto Morales with the Alameda County Sheriff’s Office told the Oaklandside that cold-plating is not new, but that authorities haven’t tracked it consistently enough to understand its full scope. Nomura put it plainly: “If you don’t know how often license plates are stolen in Oakland, you don’t know how often this is going to happen.”

The problem extends beyond swapped plates. Oakland residents on Reddit have reported seeing cars missing plates entirely, and at least one user described spotting a vehicle with a handmade plate substitute.

While Nomura’s stop ended without physical harm, her experience points to a larger tension forming around automated surveillance technology. The Oakland Police Department and the Alameda County Sheriff’s Office have both credited speed cameras with helping apprehend large numbers of suspects since installation. But the technology carries real risks for innocent people when it isn’t used carefully.

Brian Hofer, a former Oakland privacy commissioner, is currently suing the city of Oakland over what he calls violations of Senate Bill 34, a state law requiring officers to use additional evidence beyond plate-reader alerts when conducting stops. Hofer says officers frequently rely on the alerts alone, skipping verification of details like vehicle make, model, and color.

His concern comes from personal experience. Hofer and his brother were once stopped at gunpoint while driving a rental car that had been previously stolen but never removed from a law enforcement database. The car was cleared, but the record wasn’t updated.

The Nomura case fits a pattern that advocates have warned about for years: automated systems move fast, but people bear the consequences when the data is wrong or incomplete. Cold-plating adds another layer of danger, because the problem isn’t the database being outdated. It’s that someone deliberately placed fraudulent information in front of the scanner.

It’s a reminder that the communities most exposed to vehicle crime, including Oakland residents who have watched plate theft become routine, are also most at risk of getting caught in the crossfire of enforcement tools designed to stop it.

A large plate-swapping operation came to light in San Francisco back in 2022, when SFPD discovered tools and evidence inside a stolen Audi suggesting the tactic was being used systematically to mask vehicles and avoid detection. That case showed the practice wasn’t casual or opportunistic. It was organized.

Nomura’s message to city officials and law enforcement is direct. Track the reports. Know how often this is happening. And build in protections so that the next person who has their plates stolen doesn’t end up facing armed officers over someone else’s crime.

“I could have been hurt,” she said. That shouldn’t be the acceptable risk that comes with owning a car in Oakland.
