A specialist police unit in England has decided not to continue using software developed by American technology company Palantir Technologies after a two-year trial examining how the system could support serious crime investigations.

The East Midlands Special Operations Unit (EMSOU), which investigates serious and organised crime across several counties, confirmed that it would not proceed with a new contract for Palantir's Foundry software.

The decision follows a trial launched in October 2024 to assess whether the technology could help investigators analyse information more effectively while maintaining ethical standards and protecting the public interest.

The development comes amid wider debate about the use of artificial intelligence (AI), data analysis and surveillance technology by law enforcement agencies and public institutions.

Why Did the Police Unit Stop Using Palantir?

EMSOU said the trial was designed to examine how Palantir's software could support police investigations while meeting appropriate standards of accountability and ethics.

However, the unit decided not to extend the arrangement after its Home Office funding ended.

Regional Assistant Chief Constable Ian Green said the decision followed an assessment of the project's expected benefits and the availability of future funding.

He explained that the unit would continue exploring innovative technology to help tackle serious and organised crime.

EMSOU also confirmed that Palantir would be required to disconnect its systems from the police force's systems and delete its data, as described in the information provided about the decision.

The unit did not disclose the precise cost of the trial or all the datasets used, citing commercial confidentiality and operational security.

What Is Palantir Foundry?

Palantir Foundry is a data integration and analysis platform designed to help organisations bring together information from different sources, organise it and examine relationships between datasets.

Its tools can support decision-making by allowing users to search large volumes of information and identify patterns that might otherwise be difficult to detect.

When used by law enforcement agencies, systems of this kind may help investigators organise evidence, examine connections between people or events, and manage complex investigations.

However, the effectiveness and appropriateness of such technology depend on how it is implemented, what information it processes and the safeguards in place.

Questions about data protection, access controls, accuracy and accountability have become increasingly important as public institutions adopt AI-assisted systems.

Which Crimes Does EMSOU Investigate?

The East Midlands Special Operations Unit investigates serious and organised crime across Derbyshire, Leicestershire, Lincolnshire, Nottinghamshire and Northamptonshire.

Its responsibilities include investigating offences such as murder, terrorism-related crimes and drug trafficking.

During the Palantir trial, data from Leicestershire Police was supplied to the Foundry platform, which uses artificial intelligence and machine learning capabilities.

However, EMSOU declined to explain precisely how the system was used in individual investigations, citing operational security concerns.

The unit's decision not to continue the project does not necessarily mean that all forms of AI or data-analysis technology will be abandoned by regional police forces.

Instead, EMSOU said it would continue examining other ways technology could support policing and efforts to combat serious crime.

Palantir Defends Its Technology

Palantir has defended the role of its software in public services, arguing that its systems can help organisations improve their operations and make better use of information.

The company has cited examples of police forces using its technology to support investigations and improve the enforcement of Clare's Law, a UK scheme that allows people to request information about a partner's history of domestic abuse.

According to Palantir, its software helped identify approximately 1,000 women in Bedfordshire whose partners had histories of domestic violence over a year.

The company has also cited cases involving organised criminal activity and investigations into serious corruption.

These examples represent the company's own account of the benefits of its technology and should be considered alongside independent assessments of its effectiveness and the safeguards surrounding its use.

Privacy and Human Rights Concerns

Palantir has faced criticism from privacy advocates and human rights organisations over the potential consequences of using advanced data-analysis systems in public services.

Critics argue that combining information from different sources can increase the risk of excessive surveillance if appropriate safeguards are not in place.

Depending on the data available and the permissions granted, analytical systems may allow organisations to examine information from a range of sources, potentially raising concerns about privacy and the rights of individuals.

Questions can also arise over how errors are identified, how decisions based on analytical tools are reviewed and whether people affected by those decisions have effective ways to challenge them.

Supporters of such technology argue that properly governed systems can help public institutions work more efficiently and identify important information more quickly.

The debate therefore centres not only on what the technology can do, but also on how it is controlled and held accountable.

Palantir's Role in the UK Health Service

Palantir's technology is also used in parts of the UK's public healthcare system.

The company has said that NHS organisations using its software have improved operational efficiency, increased the number of procedures performed and reduced delays in discharging patients.

Among the organisations it has identified are University Hospitals of Leicester and Sherwood Forest Hospitals.

However, its involvement in the National Health Service has also attracted criticism.

Amnesty International UK has campaigned against a major NHS England contract with Palantir, raising concerns about the company's human rights record and the implications of its involvement in public healthcare.

The disagreement reflects a broader debate about whether the potential benefits of advanced data systems outweigh concerns about privacy, public trust and the governance of sensitive information.

Concerns About AI in Military Operations

Palantir has also faced scrutiny over its defence-related technology, including AI-enabled systems designed to support military planning and operations.

Critics have questioned whether AI-assisted tools could generate inaccurate recommendations or contribute to decisions with serious consequences, including the possibility of civilian casualties.

There are also concerns about whether military personnel working under intense time pressure might rely too heavily on computer-generated recommendations.

Palantir has responded that it provides software and that customers control how the technology is used, with data processed according to their instructions.

Nevertheless, the debate highlights the importance of human oversight, reliable information and clear accountability when AI systems are used in high-stakes environments.

What Happens Next?

EMSOU's decision means the unit will not proceed with a new contract following the trial.

The experience may contribute to wider discussions about how police forces evaluate new technology, particularly when projects depend on public funding and involve sensitive information.

For law enforcement agencies considering similar systems, important questions include whether the technology delivers measurable benefits, whether its costs are justified and whether appropriate safeguards protect privacy and human rights.

The decision also demonstrates that public institutions may choose not to continue technology projects when funding, operational requirements or assessments of their future value do not support an extension.

EMSOU has indicated that it will continue exploring technological solutions to help investigate serious and organised crime.

Conclusion

The East Midlands Special Operations Unit has decided not to renew its arrangement with Palantir after a two-year trial of the company's Foundry data-analysis software.

The unit said the decision followed an assessment of the project's potential benefits and future funding, while confirming its continued interest in using technology to support policing.

The development comes amid ongoing debate about AI, data privacy and the responsibilities of companies supplying advanced technology to public institutions.

Although Palantir maintains that its software can improve public services and investigations, privacy and human rights advocates continue to call for strong safeguards and accountability.

As AI becomes more widely used in policing, healthcare and military operations, public confidence will depend on transparent decision-making, appropriate oversight and evidence that these systems serve the public interest.
