At Jones Walker, we look beyond today’s challenges and focus on the opportunities of the future. Since our founding in May 1937 by Joseph Merrick Jones, Sr., and Tulane Law School graduates William B. Dreux and A.J. Waechter, we have consistently asked ourselves a simple question: What can we do to help our clients succeed, today and tomorrow?

One of my favorite Steven Spielberg movies is the 2002 dystopian thriller Minority Report, in which "precogs" working for the "Precrime" unit predict murders before they happen, allowing arrests for crimes not yet committed. Recently, Pennsylvania attorneys at the Philadelphia Bench-Bar Conference raised an alarm that AI surveillance could soon create such a world – mass rights violations due to biased facial recognition, unregulated predictive policing, and "automation bias," the dangerous tendency to trust computer conclusions over human judgment.

The comparison may no longer be hyperbole. Although we haven't created mutant psychics, we've built AI surveillance claiming to predict crimes, locations, and violence timing. Unlike Spielberg's film, where technology worked relatively well, real-world predictive policing has been documented to have bias, opacity, and constitutional issues that alarm organizations considering these tools.

Facial Recognition Bias: The Documented 40-to-1 Accuracy Gap

One Philadelphia criminal defense attorney at the conference emphasized that the core issue with AI in law enforcement isn't the technology itself but "the physical person developing the algorithm" and "the physical person putting his or her biases in the program." The data confirms this concern with devastating precision.

The landmark 2018 "Gender Shades" study by Joy Buolamwini of MIT Media Lab and Timnit Gebru (then at Microsoft Research) found that commercial facial recognition systems show error rates of just 0.8% for light-skinned men but 34.7% for darker-skinned women — a 40-fold disparity. A 2019 National Institute of Standards and Technology (NIST) report, which tested 189 facial recognition algorithms from 99 developers, found that African American and Asian faces were between 10 and 100 times more likely to be misidentified than white male faces.

Another panelist highlighted that gait recognition and other biometric identification tools display "reduced accuracy in identifying Black, female and elderly people." The technical limitations extend beyond demographics: gait recognition systems struggle with variations in clothing, occlusion, viewing angles, and lighting conditions — exactly the real-world circumstances law enforcement officers encounter.

Automation Bias in Criminal Justice: Why Police Trust Algorithms Over Evidence

Panelists also warned about "automation bias," describing how "people are just deferring to computers," assuming AI-generated analysis is inherently superior to human reasoning. Research confirms this tendency, with one 2012 study finding that fingerprint examiners were influenced by the order in which computer systems presented potential matches.

The consequences are devastating. At least eight Americans have been wrongfully arrested after facial recognition misidentifications, with police in some cases treating software suggestions as definitive facts — one report described an uncorroborated AI result as a "100% match," while another said officers used the software to "immediately and unquestionably" identify a suspect. In most cases, basic police work, such as checking alibis or comparing tattoos, would have eliminated these individuals before arrest.

Mass Surveillance Infrastructure: Body Cameras, Ring Doorbells, and Real-Time AI Analysis

Minority Report depicted a surveillance state where retinal scanners tracked citizens through shopping malls and personalized advertisements called out to them by name. But author Philip K. Dick — who wrote the 1956 short story that inspired the film — couldn't have imagined the actual police surveillance infrastructure: body cameras on every officer, Ring doorbells on every porch, and AI systems analyzing it all in real time. (In fact, consumer-facing companies like Ring have partnered with law enforcement to provide access to doorbell cameras, effectively turning residents' home security devices into mass surveillance infrastructure – some say without homeowners' meaningful consent.) Unlike Spielberg's film, where the Precrime system operated under federal oversight with clearly defined rules, real-world deployment is happening in a regulatory vacuum, with vendors selling capabilities to police departments before policymakers understand the civil liberties implications.

These and other examples reveal a fundamental flaw in predictive policing that Minority Report never addressed: the AI systems cannot distinguish between future perpetrators and future victims. Current algorithms struggle to differentiate the two, and research suggests they would require "a 1,000-fold increase in predictive power" before they could reliably pinpoint crime. Like the film's Precrime system that operated on the precogs' visions without questioning their accuracy, real-world police departments are deploying predictive policing tools without proof that they perform better than traditional police work.

What Organizations Must Do Now: AI Surveillance Compliance Requirements

For any entity developing, deploying, or enabling AI surveillance systems in law enforcement contexts, three immediate actions are critical:

Mandate rigorous bias testing before deployment. Document facial recognition error rates across demographic groups. If your system shows disparate accuracy rates similar to those documented in the Gender Shades study — where darker-skinned individuals face error rates forty times higher — you're exposing yourself to civil rights liability and constitutional challenges under Fourth and Fourteenth Amendment protections.

Require human verification of all consequential decisions. AI-generated results should never serve as the sole basis for arrests, searches, or other rights-affecting actions. Traditional investigative methods — alibi checks, physical evidence comparison, witness interviews — must occur before acting on algorithmic suggestions to comply with probable cause requirements.

Implement transparency and disclosure requirements. Police departments should maintain public inventories of AI tools used in criminal investigations and disclose AI use in police reports to ensure prosecutors can meet their constitutional obligations under Brady v. Maryland to share this information with criminal defendants.

Bottom Line: AI Surveillance Legal Risk

Minority Report ends with the dismantling of Precrime after the conspiracy is exposed — a moral conclusion showing that no amount of security justifies sacrificing individual freedom and due process. Twenty-three years later, law enforcement agencies are making the opposite choice. Police departments worldwide are treating Spielberg's cautionary tale as an implementation manual, deploying the very systems Dick and Spielberg warned against. Argentina recently announced an "Applied Artificial Intelligence for Security Unit" specifically to "use machine learning algorithms to analyze historical crime data to predict future crimes." Researchers at the University of Chicago claimed 90% accuracy in predicting crimes a week before they happen. The UK's West Midlands Police researched systems using "a combination of AI and statistics" to predict violent crimes.

As the Philadelphia lawyers emphasized, the problem isn't the technology — it's the people programming it and the legal framework (or lack thereof) governing deployment. Without rigorous bias testing, mandatory human oversight, and transparency requirements, AI surveillance will do precisely what Precrime did in the film: create the appearance of safety while systematically violating the constitutional rights of those the algorithm flags as "dangerous" based on opaque criteria and historical prejudices embedded in training data.
