Fifteen days of Alain Vizcay Osorio’s life went into a Kentucky jail cell because a detective asked a face-matching algorithm who was standing in a bank photograph and then signed a sworn complaint as though he had done the detecting himself. On November 9, a federal judge in Covington said the thing the Fourth Amendment has implied all along: probable cause cannot be outsourced to a black box, and a badge does not buy immunity for pretending otherwise.
The crime was small, and it happened without a victim. On August 30, 2024, a man calling himself Ernesto Ramirez walked into the Heritage Bank in Florence, Kentucky, handed a teller a Texas operator’s license and tried to cash a check that looked forged. The teller did not believe the license, refused the check, and the man left with nothing. A ceiling camera got his face on the way in and on the way out. Memorandum Opinion and Order, Osorio v. Kilmer
That is the entire event, and no money moved. The only thing the case ever produced was a photograph, and the photograph is what cost Osorio his January.
Alain Vizcay Osorio — 15 Days for a Face That Was Not His
Detective Ryan Kilmer, working the case a couple of weeks later, discovered the Texas license was fake and turned to the bank’s footage. He screenshotted the suspect’s face and ran it through AI facial-recognition software against a booking photograph and a public Facebook profile picture. The software returned a hit. Kilmer accepted it as identification, and the complaint he signed told a judge he had used investigative tools and compared the images himself. Reuters
The Facebook account belonged to someone using the name Yony Smith Npoles Charon. Nothing in the record explains how Kilmer got from that name to Osorio, a Nebraska man whose booking photo was already in a database. A warrant issued on the strength of the complaint. Florida officers arrested Osorio on January 9, 2025. He was extradited to Boone County, Kentucky, charged with two counts of possessing a forged instrument, arraigned on January 23 and released on bond the following day.
Count the days. January 9 to January 24 is 15 of them, in two states, for a check that never cleared. Prosecutors dismissed the indictment with prejudice on May 7, 2025, after Osorio proved he was at work in Nebraska that day. Four months to believe a timesheet.
The photographs, once anybody bothered to put them side by side, showed different head shapes, different haircuts, different facial features and different complexions. The only trait the two men shared was that both were Black and had facial hair. A booking photo is not a fingerprint. It is a picture of a face that a program was asked to rank, and the program was never asked to say no. The Economic Times
Ryan Kilmer — Investigative Tools Was a Euphemism for a Screenshot
Osorio sued on January 8, 2026, one year after the arrest, alleging false arrest, false imprisonment, malicious prosecution, assault, battery and a claim for punitive damages under federal and Kentucky law. Kilmer moved in April to have the case thrown out on the pleadings and argued that qualified immunity shielded him, because no prior court had held that this exact maneuver was unconstitutional.
That is the standard machinery of American policing, and it usually works. Qualified immunity does not ask whether an officer was wrong; it asks whether a reasonable officer would have known the conduct was unlawful at the time, which is how the doctrine ends up protecting what a layperson would call obvious misconduct. Kilmer’s lawyers maintained he did nothing wrong. The court took Osorio’s allegations as true and let the case live.
What makes the complaint more than a paperwork dispute is the department’s own rulebook. Florence Police Department policy described facial recognition as advisory and stated plainly that a match does not establish probable cause without further investigation. Kilmer, according to the complaint, did no further investigation. He did not check whether Osorio was in Kentucky that day. He did not ask why a Nebraska man would cash a forged check in a Florence branch. The policy said look further. Nobody looked.
Judge S. Chad Meredith — The Magic 8 Ball Now Has a Docket Number
US District Judge S. Chad Meredith denied the motion on November 9, refused to grant immunity at the pleading stage, and allowed Osorio to file a fuller complaint. His reasoning is the part worth keeping. He imagined a detective who shakes a Magic 8 Ball at passersby, gets an affirmative answer about one of them, and then tells a magistrate he used investigative tools to make the match. The judge’s point was not that the toy is funny. It was that the unconstitutionality of trusting it exclusively is so plain that no earlier case is required to establish it. Then he said the quiet part about the software: facial recognition is likely better than a Magic 8 Ball, and trusting it without corroboration is not much different in principle.
Meredith also found good reason to believe the warrant would never have issued if Kilmer had described how he actually reached his conclusion. That is the sentence that should worry every department running one of these systems. The constitutional problem was not the algorithm. It was the affidavit that made the algorithm sound like police work.
Two limits belong in the record. The ruling sits at the pleading stage, where the court must accept the plaintiff’s story as true. Discovery could still hand Kilmer his immunity back, and his side has denied wrongdoing throughout. But a federal judge has now written, on the record, that a detective cannot hand the probable-cause question to software and collect a warrant. Whatever happens to this case, that sentence is now citable.
Florence Police Department — The Rule Was Already Written and Already Ignored
The uncomfortable detail for every agency in the country is that Florence had the guardrail, and the guardrail said the match was a lead, not an answer. Somebody still took a lead, dressed it as a conclusion, and put a man on a plane from Florida to Kentucky. Policy without a consequence attached is a suggestion, and this case is what a suggestion costs when it meets a felony charge.
There is a second bill coming, and it is not Osorio’s. The city of Florence now pays to defend a detective personally against six claims in federal court, in a case that will depose its officers about how the system is used rather than how the policy says it is. Departments that have never audited a single match should read the opinion before their own name lands in a caption. Reuters, on an Arizona appeals court and AI-generated evidence
Axel’s Take — Fifteen Days Is Not a Footnote in Somebody Else’s Lawsuit
Here is the human arithmetic that courts file under damages and never under cost. Osorio lost 15 days of his life, a job’s worth of income, and the ordinary assumption that a police officer who accuses you of a felony has looked at your face. He was indicted. He was extradited. He spent a month of 2025 clearing a name he never dirtied. The system calls that an arrest with a lawful warrant and moves on to the next file.
The pattern is widening faster than the doctrine. Reuters has documented an Arizona appellate court reversing a judge over an AI-generated victim video, a Georgia prosecutor disciplined over AI errors in a murder case, and a federal judge warning the Justice Department about its AI use in an immigration case. Different courts, same answer: the tool can suggest, the officer must verify.
The deeper failure is institutional. Police departments bought face-matching systems the way towns bought plate readers, one procurement at a time, with no bench test and no published error rate. Then they wrote advisory policies, which is a way of saying the vendor’s confidence score became probable cause the moment a detective was in a hurry. Osorio was in a hurry’s path, and the gap between what a system outputs and what a badge is allowed to believe is now a courtroom question from Kentucky to Florida.
Meredith’s opinion will not stop a single arrest. What it does is remove the excuse. A detective can no longer say he trusted the software in good faith and expect a courtroom to nod, because a federal judge has now compared that trust to a plastic fortune-telling toy and meant it as a legal standard rather than an insult. The 15 days are gone either way. The question the case leaves behind is smaller and harder: how many other people are sitting in how many other cells because nobody in the chain asked the software to show its work.
