Policing the Future: The Role of AI and Machine Learning in Law Enforcement

Written by Andrew Mills on 2025-07-28

Artificial intelligence is increasingly being deployed across nearly every sector — from finance to medicine, logistics to agriculture. But one of the most controversial and complex applications is in law enforcement.

In recent years, AI and machine learning have been touted as tools to modernise policing: streamlining investigations, enhancing surveillance, automating paperwork, and helping officers identify patterns across vast data sets that no human could parse alone.

Yet for every promise of innovation, there’s a parallel concern about bias, ethics, and overreach. Can we trust algorithms with decisions that impact human liberty? How do we prevent AI from reinforcing structural inequalities? And where should the line be drawn between efficiency and human rights?

In my opinion, the key lies not in rejecting AI altogether — but in building systems with transparency, oversight, and purpose. The future of policing isn’t about replacing humans. It’s about augmenting them — thoughtfully.


The Promise: Speed, Scale, and Smarter Investigations

Modern police forces are under enormous pressure. Budget cuts, staff shortages, and rising demand mean that many departments are under-resourced and overburdened. In this context, AI offers a compelling proposition.

Machine learning models can:

  • Sort and prioritise digital evidence from devices, bodycams, or CCTV footage
  • Identify suspects based on known traits, prior cases, or facial data
  • Analyse crime patterns to predict hotspots and allocate resources
  • Process reports, witness statements, and case files far faster than a human ever could

This isn’t hypothetical. In many jurisdictions, AI systems already assist in fraud detection, gang intelligence, and even real-time emergency call triage.

From what I’ve seen, the right systems can dramatically reduce investigative bottlenecks, allowing officers to focus on frontline work rather than drowning in paperwork.


A Real-World Example: Remote AI Surveillance

At Obsidian Reach, we’re developing a new generation of AI-powered surveillance cameras designed for use in remote or under-monitored areas. These compact, battery-efficient units combine edge AI processing with intelligent object detection, anomaly recognition, and long-range monitoring.

They can detect:

  • Unusual vehicle or foot traffic in restricted zones
  • Repeated visits to high-risk areas
  • Loitering or pattern-based behaviour suggestive of reconnaissance
  • Known persons of interest using biometric cues (when legally appropriate)

These systems are designed to operate with minimal human oversight, delivering alerts and flagged footage to central units without requiring constant live monitoring.

This has major implications for rural law enforcement, border security, and critical infrastructure protection — where human patrols are often scarce or spread thin.


The Problems: Bias, Discrimination, and Dystopia

However, the story is far from one-sided.

One of the most cited cautionary tales is Amazon Rekognition — a facial recognition system that was tested by police departments in the United States. Independent analysis found that the system showed racial and gender bias, misidentifying people of colour and women at significantly higher rates than white males.

This is not just a technical flaw — it’s a civil rights issue. False identifications can lead to wrongful arrests, unjustified surveillance, and community distrust. When an algorithm can influence who gets stopped, searched, or flagged as a suspect, the margin for error must be nearly zero.

And then there’s the deeper ethical question: should AI be used to predict future crime?

The so-called “Minority Report” problem arises when AI models are trained on biased crime data, which then gets used to predict future criminal behaviour — creating feedback loops that reinforce existing policing biases. Neighbourhoods that were over-policed in the past get flagged as high-risk again, even if circumstances have changed.

This kind of predictive policing is deeply flawed, in my view. AI must never be used to justify action before a crime has occurred — only to support investigations grounded in fact.


Accountability and Oversight: Non-Negotiables

To navigate this space responsibly, I believe several principles must be followed:

  1. Transparency: AI models used in law enforcement must be auditable and explainable. Black-box decision-making is unacceptable.
  2. Bias Audits: Every system must undergo rigorous, ongoing testing for racial, gender, and socioeconomic bias.
  3. Human-in-the-Loop: AI should assist, not decide. Final decisions must always rest with trained officers or judicial authorities.
  4. Legal Safeguards: Clear policies should govern where and how AI is used — including data retention, biometric consent, and the right to appeal algorithmic decisions.

Without these safeguards, AI in policing risks becoming an enabler of injustice rather than a tool for safety.


The Path Forward: Smart Tech for Smart Justice

From my experience, the most successful AI deployments in law enforcement are the ones that solve real problems without creating new ones.

AI should not be used to criminalise communities. It should be used to accelerate investigations, protect officers, and uncover truth faster than any human task force alone could manage.

Used responsibly, machine learning can help detect patterns in cybercrime, identify victims of trafficking across border databases, or trace the origins of weapons and drugs. These are areas where AI can scale human insight, not replace it.

As we move forward, companies like Obsidian Reach will continue building systems that respect privacy, demand oversight, and put intelligent automation in the service of justice — not just enforcement.


AI in Law Enforcement Must Serve the People*

AI and ML have a legitimate role to play in the future of policing — but only if they are built with integrity, inclusivity, and rigorous ethical standards.

The goal must be not simply to catch more criminals, but to create systems that are fair, efficient, and accountable. That means recognising AI’s potential — and also its limits.

In my opinion, the conversation shouldn’t be about whether we use AI in law enforcement. It should be about how we use it — and who it ultimately serves.

Because justice is not just about outcomes. It’s about process. And AI, if done right, can make that process smarter, faster, and more equitable.
