Sandra Barker spent 39 days in a North Dakota jail. She was 56 years old, a grandmother, and she had done nothing wrong.
The case against her began not with a detective’s hunch or a witness tip but with an algorithm — an artificial intelligence system deployed by the state to detect Medicaid fraud. The AI flagged Barker’s billing records as suspicious. Based largely on that automated output, North Dakota’s Bureau of Criminal Investigation arrested her, and prosecutors charged her with multiple felonies. She faced years in prison. And the machine was wrong.
The story, first reported in detail by the Grand Forks Herald, is more than one woman’s nightmare. It’s a warning shot about what happens when governments lean on artificial intelligence to police their citizens — and what happens when no one checks the machine’s work before lives are destroyed.
Barker worked as a personal care assistant in North Dakota, providing in-home services to people on Medicaid. The state’s Department of Human Services had contracted with Conduent, a technology services company, to process Medicaid claims and, critically, to use AI-driven analytics to identify potential fraud. The system flagged Barker. Investigators took the flag and ran with it, building a criminal case that alleged she had billed for services she never provided.
Except she had provided them.
According to the Herald’s reporting, the AI system’s analysis contained significant errors. The algorithm apparently failed to account for legitimate billing patterns and misinterpreted data in ways that made lawful claims look fraudulent. Barker was arrested in 2023, booked into the Ward County Jail, and held for 39 days before she could post bond. She lost income. She lost time with her grandchildren. She lost her sense of safety in a country that promises its citizens are innocent until proven guilty.
The charges were eventually dropped. But “eventually” is doing enormous work in that sentence. For months, Barker lived under the weight of felony accusations, her reputation in tatters, her freedom conditional on a court’s calendar. All because a computer said she was a criminal.
The Machinery of Automated Suspicion
North Dakota’s case isn’t an isolated incident. It sits at the intersection of two accelerating trends: the expansion of government surveillance infrastructure and the increasing reliance on AI to interpret the data that infrastructure collects. Across the United States, federal and state agencies are deploying algorithmic tools to monitor benefits programs, tax filings, immigration status, and criminal behavior. The appeal is obvious. These systems can process millions of records in hours, flagging anomalies that would take human auditors months to find. They promise efficiency. They promise savings. What they don’t promise — and can’t guarantee — is accuracy.
The problems are well-documented. In Michigan, an automated fraud-detection system for unemployment insurance falsely accused more than 40,000 people of fraud between 2013 and 2015, according to reporting by the Detroit Free Press. The state’s own review later found a 93% error rate. People had wages garnished. Some lost their homes. In the Netherlands, a tax authority scandal involving an algorithmic fraud-detection system that disproportionately targeted minority families brought down the entire Dutch government in 2021.
And yet the tools keep proliferating. The IRS has invested in AI to detect tax fraud. States use predictive algorithms to flag child welfare cases. Police departments across the country employ facial recognition, predictive policing software, and automated license plate readers that log the movements of millions of vehicles daily. The surveillance net grows wider and finer simultaneously, and AI is the engine pulling it taut.
The fundamental problem isn’t that these systems exist. It’s that they’re treated as authoritative when they are, by design, probabilistic. An AI fraud-detection model doesn’t determine guilt. It calculates likelihood. It produces a score, a flag, a recommendation. But somewhere between the algorithm’s output and a prosecutor’s charging decision, that probability hardens into certainty. The flag becomes the case. The score becomes the evidence. And the human beings who are supposed to exercise judgment — investigators, prosecutors, judges — defer to the machine.
That’s what appears to have happened to Sandra Barker. The Bureau of Criminal Investigation received the AI’s output and, according to the Herald’s account, conducted an investigation that leaned heavily on the algorithmic findings without sufficiently verifying them against ground truth. Nobody knocked on enough doors. Nobody cross-referenced enough timesheets. The machine said fraud, so fraud it was.
This pattern has a name in academic circles: automation bias. It’s the well-documented tendency of human decision-makers to favor suggestions from automated systems, even when contradictory evidence is available. Studies in aviation, medicine, and criminal justice have repeatedly shown that when a computer says one thing and a human’s own assessment says another, the human tends to go with the computer. In low-stakes environments, this might mean a slightly less optimal route on your GPS. In criminal justice, it means an innocent woman in a jail cell.
The implications extend far beyond individual cases. Mass surveillance systems powered by AI create what scholars at the AI Now Institute have called an “asymmetry of power” — the state knows everything about you, and you know nothing about the system judging you. When Sandra Barker was arrested, she had no way to examine the algorithm that flagged her. She couldn’t challenge its assumptions, audit its training data, or question its methodology. She was confronting an accuser she couldn’t see, built by engineers she’d never meet, operating under logic no one in the courtroom fully understood.
This opacity is a feature, not a bug, for the companies that build these systems. Conduent, the firm involved in North Dakota’s Medicaid processing, has faced scrutiny in multiple states. In 2023, the Associated Press reported on widespread problems with Conduent’s Medicaid eligibility systems in several states, including Texas and Indiana, where technical failures led to eligible people being wrongly denied coverage. The company has maintained that its systems work as designed and that errors are the responsibility of the state agencies that deploy them. That defense — it’s not our fault how they use it — is a recurring theme in the AI accountability vacuum.
No one owns the mistake. The algorithm’s developer says the tool is only advisory. The government agency says it relied on the developer’s technology. The prosecutor says she relied on the investigators. The investigators say they relied on the data. And the person whose life gets wrecked has no one to hold accountable and no clear path to make herself whole.
Barker’s attorney has indicated she may pursue legal action against the state, according to the Grand Forks Herald. But even successful lawsuits don’t fix the underlying architecture. The systems remain in place. The data keeps flowing. The algorithms keep flagging.
So where are the guardrails? In theory, the justice system itself is supposed to be the check. Prosecutors have ethical obligations to verify evidence before filing charges. Judges are supposed to scrutinize the basis for arrests and detention. Defense attorneys are supposed to challenge the state’s case. But these human safeguards are under enormous strain. Public defenders carry crushing caseloads. Prosecutors face political pressure to show results. And very few lawyers or judges have the technical literacy to meaningfully interrogate an AI system’s output.
Some states are beginning to act. Colorado passed a law in 2024 requiring impact assessments for high-risk AI systems, including those used in government decision-making. The European Union’s AI Act, which began taking effect in stages this year, classifies law enforcement and benefits-administration AI as high-risk and imposes transparency and accuracy requirements. But in most of the United States, there is no legal framework specifically governing how AI-generated evidence or AI-driven investigations must be validated before they can be used to deprive someone of liberty.
That gap is staggering when you consider the scale. The federal government processes roughly 100 million Medicaid claims per month. The IRS handles more than 150 million individual tax returns annually. The Department of Homeland Security monitors billions of border-crossing and immigration records. Each of these systems increasingly relies on automated analysis. Each generates flags that can trigger investigations, audits, denials, and arrests. The denominator is enormous. Even a small error rate — say, 1% — means hundreds of thousands of people wrongly targeted every year.
And error rates in these systems are rarely as low as 1%.
The National Institute of Standards and Technology has repeatedly found significant accuracy disparities in facial recognition systems, with error rates for Black and Native American faces running 10 to 100 times higher than for white faces. Predictive policing algorithms trained on historically biased arrest data tend to direct police disproportionately to minority neighborhoods, creating feedback loops that reinforce the very disparities they reflect. Fraud-detection models trained on incomplete or skewed datasets — like the one that apparently ensnared Barker — can systematically misidentify legitimate behavior as criminal.
The people most likely to be harmed are those least equipped to fight back. They’re low-income workers like Barker, who depend on government programs and can’t afford private attorneys. They’re immigrants whose visa status depends on opaque algorithmic risk scores. They’re residents of over-policed neighborhoods where every data point feeds a system primed to see threat.
Mass surveillance has always carried this risk. What AI adds is speed, scale, and a veneer of objectivity that makes the results harder to question. A human investigator who targets someone unfairly can be cross-examined, challenged, held accountable for bias. An algorithm that produces the same biased outcome is treated as math. Neutral. Scientific. Trustworthy.
It isn’t.
Sandra Barker is home now. The charges are gone. But the 39 days don’t come back. The months of anxiety don’t come back. The mugshot that appeared in local media doesn’t disappear from the internet. And the AI system that put her through it? As far as public reporting indicates, it’s still running.
That should trouble everyone — not just the people it’s already gotten wrong, but the millions of Americans whose daily lives are increasingly mediated, monitored, and judged by systems they can’t see, can’t question, and can’t appeal. The promise of AI in government was better decisions, faster. The reality, in at least one grandmother’s case in North Dakota, was the opposite. A worse decision, made faster, with consequences that no software update can undo.
The question now isn’t whether AI will continue to be used in surveillance and law enforcement. It will. The question is whether the institutions deploying these tools will build in the skepticism, the verification, and the accountability that the technology itself cannot provide. Based on the evidence so far, the answer isn’t encouraging.
