AI is already used in police work for practical information-processing tasks: sorting digital evidence, redacting material, transcribing and translating calls, summarising case files, triaging non-emergency contacts, supporting facial-recognition searches and automating administrative work. Mixed reality (MR)—including augmented-reality (AR) displays—is at a much earlier stage. Police-technology literature describes possible hands-free information displays, mapped crime scenes and virtual markers, but the available evidence does not show that MR is routine across police forces or that it has proven outcome gains.
The distinction matters. An AI system may accelerate a search or produce a candidate for an investigator to check; it does not replace legal authority, professional judgment or evidence standards. An MR headset may present information in a user’s field of view; that possibility is not evidence of a standard, field-tested police capability.

What police departments use AI for
A June 2026 UK Home Office factsheet groups police AI uses into four broad areas. These are government-identified use cases, not a claim that every force has deployed every tool.

- triaging and analysing digital evidence;
- redacting text, audio and video before disclosure or release;
- summarising case files;
- supporting disclosure decisions;
- detecting suspected deepfakes; and
- digitising paper files.
These functions change the order and speed of review, not the legal status of the underlying material. Investigators still need to verify what a system has found, preserve provenance and decide whether information is relevant and admissible.
Finding wanted or missing people
Facial recognition and automated number-plate recognition can help search images or vehicle data for investigative leads. A system compares new material with a reference database and returns possible matches. The result is a prioritised candidate list, not an automatic finding of identity or guilt.
Control-room and contact-centre support
The same UK factsheet describes AI support for transcribing calls, classifying crime and triaging non-emergency 101 contacts. Triage can help route a routine report to the right queue or identify information that needs a faster human response. The UK government says it does not currently support AI answering 999 emergency calls. That is a UK policy position and should not be generalized to every country or police service.

Translation and back-office work
Translation of documents and other repetitive administrative tasks are also identified uses. Automation can reduce typing and filing time, but forces must still check translations, protect sensitive data and retain an accountable human decision-maker for consequential actions.
Facial recognition: what the system does and what it cannot prove
Facial recognition uses AI to compare faces in an image or video with faces held in a reference database. Police applications generally fall into two operational patterns.
| Mode | Police task | What the result means | Human responsibility |
|---|---|---|---|
| Live facial recognition | Compare faces captured by a camera during a live deployment with a watchlist or other authorised reference set. | A possible alert requiring assessment under the force’s policy. | Officers must apply the governing policy, assess the alert and take proportionate action. |
| Retrospective facial recognition | Search a face from previously collected footage, an image or another exhibit against a database such as the Police National Database. | An investigative lead, not proof of identity or culpability. | A trained user and investigating officer visually assess potential matches and place the result in the wider investigation. |
The UK Home Office states: “A retrospective facial recognition match is only ever one piece of intelligence, as part of a wider police investigation.” That qualification should appear whenever a retrospective search is described. A candidate must be checked against other evidence, including the image quality, time and location, witness information and the possibility of an innocent explanation.

The UK legal and policy setting
For live deployments in England and Wales, Home Office material says forces must follow College of Policing Authorised Professional Practice and comply with the Data Protection Act 2018, Human Rights Act 1998, Equality Act 2010, Police and Criminal Evidence Act 1984, the Surveillance Camera Code of Practice and published police policies. The precise legal position can change: the Home Office launched a consultation in December 2025 on a new framework for law-enforcement biometrics and facial recognition, so a force should check the current rules before deployment.
How to interpret the reported 99% figure
The Home Office factsheet reports: “At the settings used by the police, testing also found that if a correct match was on the database, the system found it in 99% of searches.” This means 99% of searches in which the correct match was on the database, at police settings, according to UK Home Office testing reported in 2025. It is a conditional search result—not a universal accuracy rate, a false-positive rate or a performance claim for every facial-recognition system. A decision-maker also needs error rates, subgroup results, image-quality conditions and the consequences of a mistaken alert.
Governance, training and civil-rights safeguards
Police AI affects privacy, liberty and access to justice, so a technically successful model is not enough. A defensible deployment needs a documented legal basis, a defined purpose, controls on access and retention, testing in the intended environment and a way for people to challenge harmful decisions.
Training and operator competence
In March 2024 testimony, the US Government Accountability Office (GAO) summarised an earlier review of seven selected federal law-enforcement agencies. All seven initially used facial-recognition services without requiring related staff training; by April 2023, two had implemented requirements. Across those selected agencies, about 60,000 searches occurred during periods when training requirements were absent. The figure is not a count of all US police searches and does not describe every agency’s current practice.
A separate GAO survey published in 2021 covered 42 federal agencies employing law-enforcement officers. Twenty reported owning facial-recognition systems or using systems owned by others. GAO recommended tracking non-federal-system use and assessing privacy, accuracy and related risks. These are historical survey findings, not a current national adoption estimate.
Testing and bias checks
Before an operational launch, a force should test the complete workflow—not just the algorithm. That includes the cameras, image compression, database quality, search thresholds, operator decisions and the action taken after an alert. Testing should report false positives and false negatives, performance across relevant demographic groups and results under realistic lighting, pose and occlusion. Independent evaluation is stronger evidence than a vendor’s internal headline metric.

Oversight and transparency
In an August 2026 update, the UK Information Commissioner’s Office described growing deployment and newer police approaches, including operator-initiated facial recognition. The ICO highlighted data-protection duties and discussed mitigations such as staff training, oversight reporting, equality-impact assessments and planned algorithm replacement in the context it reviewed. Those measures describe the regulator’s work in that context; they should not be assumed to exist at every force.
The UK Home Office says PoliceAI began mobilising in April 2026 and formally launched in June 2026. It describes a planned public register of police AI tools, their purposes, identified risks and mitigations, while disclosure policy was still being developed. Because that organisation and register are time-sensitive, readers should verify their current status before relying on them.
Operational safeguards checklist
- Purpose limitation: define the decision the tool supports and prohibit unrelated uses.
- Legal authority: document the statutory power, policy and human-rights assessment.
- Data controls: record data source, quality, representativeness, retention and deletion rules.
- Human review: specify who must verify an output and what evidence they must consider.
- Auditability: log searches, settings, users, outputs, overrides and subsequent actions.
- Training: require role-specific instruction before access and refresher training thereafter.
- Redress: provide complaint, correction and review routes where a person is affected.
- Public reporting: disclose the tool’s purpose, known risks, safeguards and material incidents.
How mixed reality could support police work
Mixed reality combines digital information with a user’s physical surroundings. Augmented reality overlays content on the real world; virtual reality largely replaces that view. A 2021 article from India’s Bureau of Police Research and Development (BPR&D) argues that AR and MR can preserve more awareness of the physical environment than fully immersive VR and discusses combining AR glasses with AI and facial recognition.

Crime-scene mapping and documentation
The BPR&D article describes a possible crime-zone workflow: map the scene, capture digital evidence and place virtual markers that remain anchored to locations. In principle, a team could use those markers to identify where an item was found, guide a later reviewer through the scene or compare a spatial record with photographs and measurements. The article describes a concept and potential workflow; it does not establish routine deployment, independent evaluation or an outcome improvement.
Hands-free situational information
An AR display could present a map, location label, safety warning or task prompt without requiring an officer to look down at a separate device. An FBI-hosted overview likewise discusses augmented-reality technology and possible police uses involving situational information and memory. Those are arguments about potential, not proof that a display improves safety, recall or decision quality in operational conditions.
What “AR glasses in policing” means today
The available sources support a cautious answer: they describe possible hands-free information displays and scene-documentation tools, but do not show that AR glasses are standard across police forces. No general conclusion should be drawn about a named headset, current procurement, a field trial or measured safety and accuracy effects without a dated force-level policy or independent evaluation.

Body-worn cameras are related, but they are not mixed reality
Body-worn cameras record the physical world; they do not overlay computer-generated information in the user’s view, so they are not MR. They matter to this topic because AI may later help manage and analyse the footage.

An OJP summary published in March 2022 described footage uses in evidentiary review, prosecutor decisions, police-action training and internal investigations. Those summaries identify practice areas; they do not show that every department achieves those effects or that cameras alone cause them.
How to compare a police AI or MR deployment
Whether a force is assessing facial recognition, evidence triage or an AR scene tool, use the same questions for every option:
- Job and context: What specific decision or workload is being addressed, and in what environment?
- Inputs: Where do images, audio, text, maps or sensor data come from? Are they accurate and representative enough for the task?
- Measured errors: What independently tested false-positive, false-negative and subgroup results apply to the actual configuration?
- Operator action: What does the user see, what must they verify and what actions are prohibited without additional evidence?
- Law and privacy: What legal authority, impact assessment and proportionality analysis support collection and use?
- Controls: Are training, role-based access, audit logs, retention limits and security procedures in place?
- Transparency and redress: Can the public learn the purpose and risks, and can an affected person challenge an error?
- Total resources: What acquisition, integration, storage, support, staffing and replacement costs will continue after the pilot?
UK funding and programme context
The UK government reports the following allocations. They are UK figures for the stated policy periods, not global police-technology spending.
| Item | Reported amount and context |
|---|---|
| Police AI support | More than £50 million in 2024–25 and 2025–26, according to the UK government. |
| Police Reform White Paper commitment | £115 million announced for AI and automation. |
| National facial-recognition system | £26 million identified separately by the Home Office. |
These allocations show policy priority, not proof that a particular tool works or that every force has access to it. Deployment decisions still depend on local legal, technical and operational assessments.
What the evidence supports—and what it does not
Current official material supports a clear conclusion: AI already assists several police workflows, especially information-heavy tasks, while facial recognition is an investigative aid that requires trained human assessment. Governance failures documented by US oversight and the safeguards described by UK regulators show why training, testing, auditability and transparency are operational requirements rather than optional extras.
Mixed reality remains primarily a proposed or emerging aid. Scene mapping, virtual markers and hands-free displays are plausible applications described in law-enforcement literature, but the available sources do not establish widespread use or proven benefits. Any claim about a specific headset, force, procurement programme or measured field outcome requires newer, direct evidence.
