Met Palantir row gets to heart of how public services should use AI

It’s bot vs bobby. The row over whether the controversial US AI company Palantir should be paid £50m to help the Metropolitan police hits to the heart of how public services will be delivered in the coming years.

A similar dynamic is playing out in hospitals, schools and town halls, but right now police chiefs are turning to AI to escape a fiscal bind. The UK’s largest police force is shrinking; a £125m funding shortfall means it faces cutting 1,150 posts. Scotland Yard wants to use AI to deploy Palantir’s systems to comb through human intelligence reports, email caches, phone records and the rest of the torrent of digital evidence trail left by 21st century crime.

The implication is clear – AI is now seen as a plausible alternative for at least some human labour in policing and is on its way to becoming a mainstay of the national security apparatus. Human police officers deal with some of society’s most vulnerable people, and also some of the most confidential data and sources. The police want AI to do it too.

Scotland Yard is not an outlier in looking at AI. Forces such as Bedfordshire and Leicestershire have used Palantir tech. Despite trying to keep out of the Palantir row by calling it an “operational matter for the Met and Mayor of London”, the Home Office is setting the pace. Shabana Mahmood, the home secretary, in January called for police to “ramp up use of AI” and to adopt the technology “at pace and scale”.

Labour has set up a national centre called Police AI and is deploying AI as an agent of efficiency in the NHS, the military and the justice system, but the problem is this: the government doesn’t have its own AI systems and the companies that could help are increasingly controversial with the public and politicians.

Sadiq Khan’s stated reason for blocking the Met’s Palantir deal was a “clear and serious breach” of procurement rules, but politics lies not far behind. He has also cited “concerns about using public money to support firms who act contrary to London’s values”. Palantir’s leaders, such as its co-founder Peter Thiel and its chief executive Alex Karp, have a knack for controversial statements. Thiel famously said the NHS makes people sick. Karp recently called the disarmament of Germany and Japan after the second world war an “overcorrection”.

Many US AI providers find themselves tainted in the public mind by a general distrust of “big tech”, a byword for concentrated power backed by vast lakes of private capital and often bending the knee to Donald Trump. Palantir, with its contracts for Trump’s ICE immigration crackdown, Israel’s military and the US defence department, has become a poster-child for what many in the public and parliament fear is big tech’s dark side.
