Cop cops it after Copilot cops out: West Midlands police chief quits over AI hallucination

(2026/01/19)


The chief constable of West Midlands Police has retired after his force used fictional output from Microsoft Copilot in deciding to ban Israeli fans from attending a football match at Birmingham club Aston Villa.

Chief Constable Craig Guildford, 52, retired from England's third-largest police force on 16 January. He was [1]due to meet his boss , Simon Foster, Police and Crime Commissioner for the West Midlands, on January 27.

He had earlier written to the chair of the House of Commons home affairs committee to apologize for incorrectly saying his officers had not used generative artificial intelligence (AI) when researching whether to block Maccabi Tel Aviv fans from attending a Europa League match against Aston Villa on 6 November 2025.

West Midlands Police made its decision to block the away fans partly based on reports of disruption at a non-existent match between Maccabi Tel Aviv and London club West Ham.

On 6 January, Guildford told MPs on the home affairs committee that officers had found this material through a Google search that did not involve use of AI functions. "We do not use AI," he said in evidence to MPs.

In a [4]letter on 12 January , however, Guildford said he had since realized that the made-up material had in fact come from a generative AI tool:

Home secretary Shabana Mahmood had earlier said she had no confidence in Guildford, although any decision on his employment was up to the West Midlands police and crime commissioner.

As well as questions over where it had found material, the force was criticized for taking an anti-Israeli stance in making its decision.

Generative AI tools have previously made up cases cited by lawyers in both the [14]US and the [15]UK . In October, consultancy Deloitte refunded A$440,000 to the Australian government after using generative AI in writing a report that [16]featured made-up references and footnotes . ®

Idiocy

Rich 2

We’re all hearing increasingly bonkers stories involving LLMs but this one is definitely up there with the barrister/solicitor/whatever that cited a fictitious case in his court filing.

I would like to think that this will mean the police and judiciary would impose a total ban on using this shit but I know that won’t happen because it would require a minuscule amount of effort

Re: Idiocy

MaChatma CoatGPT 2.0

I absolutely agree on the use of LLMs. Letting some dimwit plod loose with one is asking for trouble.

The worrying thing for me is that this team, and others located nearby, are actually violent scumbags with a long history of appalling behaviour. If you want to see how low some fans will go try Beitar Jerusalem. They proudly boast of being the world's most racist club. They make Millwall in the 1970s look like a Girl Guide's picnic.

Re: Idiocy

Tom Graham

The far more worrying thing is a large English police force being led by a liar and an imbecile who is working for and on behalf of Islamist anti-Semites.

And that this has been shown to be true of several other forces.

Re: Idiocy

Irongut

Banning known violent football hooligans is not anti-semitic. I'd ban football in general.

Re: Idiocy

Tom Graham

Fabricating "intelligence" to justify banning a football team from Israel at the behest of Islamist extremists who are threatening actual violence if you do not comply seems very anti-Semitic to me.

Re: Idiocy

Paul Hovnanian

Perhaps. But what would people call it if AI had recommended stopping a music festival near Gaza in 2023? Anti-Semitic, or amazingly prescient?

We don't know how AI works internally. So we can't ask it to justify it's conclusions. That will be on us, the users. And if we've got to do that, we may as well do the initial analysis as well.

Re: Idiocy

Tom Graham

Would you ban sports in general?

And music?

And keeping dogs as pets, and non-consanguineous marriage, and women being allowed to show their hair in public?

Funny lot, the Reg commentariat. I would never have had a technology news website as a gathering place for fans of Jeremy Corbyn.

Re: Idiocy

Doctor Syntax

Given that Microsoft is almost universal on work desktops and that Microsoft are pushing Copilot into all aspects of it as hard as possible it might require a good deal more than a miniscule amount of effort to keep it from being used. Perhaps double up staff with a monitor peering over every user's shoulder to ensure they don't use it, even accidentally.

Greybearded old scrote

It would require a modicum of understanding. Non -techies are going to believe what the salesthings tell them, and what else would you expect? I know for sure that I don't have enough relevant knowledge to perform as a copper.

Re: Idiocy

Tom Graham

The claim that AI hallucinated the fictional "intelligence" about Israeli football fans is very likely a complete lie, like all the rest of the evidence that Guildford gave to the Home Affairs Committee.

The more verisimilar explanation is simply that the police fabricated it themselves, and, being so obviously profoundly intellectually challenged, they assumed that nobody would ever check their claims.

I doubt it. See [1]Hanlon's Razor .

Re: Idiocy

Tom Graham

Fair enough, but I prefer Occam's razor.

The police are lying.

Given that we already know they were lying.

Vs

The police managed to get AI to hallucinate the exact false information they were looking for.

"AI hallucinated these claims" is the new "someone hacked my social media account".

I think you may have a fundamental misunderstanding of Occam's razor. (And Hanlon's razor.)

Re: Idiocy

Tom Graham

Sorry, guess again.

Never been arrested, no speeding conviction, never even got points.

What I have experienced is three separate cases of child abuse and sexual assault where the police went out of their way to protect the perpetrator, two of whom were Muslim, the third was the spouse of a police officer.

You don't have to have a criminal record to recognise the corruption, incompetence and criminality across every police force, from top to bottom.

The scary part is that wasn't an isolated case. I've seen several dozen instances of that, and those are just the ones that make the news.

Not nearly as uncommon as you may imagine. 811 cases and counting. https://www.damiencharlotin.com/hallucinations/ The guy is doing quite a service by collecting the data. Embarrassing to the ai cos.

Re: Idiocy

Gordon 10

Im going to get downvoted here but AI isnt the problem here.

Its functionally identical to trusting an employee - getting challenged on that trust....then not verifying.

This was a management 101 failure not a technology one regardless of the use of AI.

Retired eh ?

Re: Fucks up catastrophically, retires at 52

Doctor Syntax

This is only part of it. He'd retired earlier and been rehired. This seems to have been due to some quirk of the pension scheme that would have made it disadvantageous to keep working but "retirement" sealed that off and he could then have been rehired without disadvantage to himself.

He seems to have had a good record in turning the force's effectiveness round but also had complaints about bullying upheld against him. Things are seldom black and white.

...he blamed the public outcry, the media and politicians for him having to retire, not his fuck up and lies. No sir it was everyone else to blame.

Not their decision

TherealCAB

It wasn't the WMP who decided that Maccabi fans couldn't attend, but it was their report.

There is a separate Safety Advisory Group involving the Council, Police and other partners who made the decision, which of course was influenced by the WMP report, which also apparently included false accusations from a Maccabi away game in The Netherlands.

Ah! The next era of humans as moral crumple zones begins

vroomik

The moral crumple zone - where human operators absorb moral and legal responsibility when (AI) systems fail.

The pattern is not new, but those type of cases will explode in number I persume, as more of the "agents" and slop "halucinated" shite will muddy the waters.

What a time to be a scapegoat!

Re: Ah! The next era of humans as moral crumple zones begins

Doctor Syntax

We may now see boards, CEOs etc. being a bit more cautious about having electronic hallucinators loose in whatever it is they run although realistically it may take a few more before "it could be me" dawns on the larger egos.

The man at the top has (belatedly) taken the blame and buggered off

Anonymous Coward

But who actually invoked Copilot to trigger the whole mess? Have they been prevented from doing it again? Are procedures for verifying now proof against a repetition?

Or do we have proof that it was Guildford who literally sat at the keyboard instead of doing his job and having subordinates gathering data?

Re: The man at the top has (belatedly) taken the blame and buggered off

Tom Graham

We don't have any proof that Copilot, or any other AI, was involved at all.

Only the word of two police officers who have been proven to already have lied to a parliamentary committee, and also claim to have lost the minutes of a meeting where Dutch police informed them of rioting by Israeli football fans.

Much more likely is that they simply fabricated the information themselves.

"AI hallucinated these false claims" is the new "someone hacked my social media account".

Re: The man at the top has (belatedly) taken the blame and buggered off

Doctor Syntax

"Or do we have proof that it was Guildford who literally sat at the keyboard instead of doing his job and having subordinates gathering data?"

I don't think anyone believes that to have been the case. His problem was in not ensuring what he said was correct and accepting the blame for that. It's been sadly lacking in public life. I can think of at least one other instance where much more drastic failure didn't lead to resignation; even to eventual promotion.

Anonymous Coward

I know, we'll drive out the poor sod who got burned by his in-house regime and is now highly sensitised, and replace them with a clueless noob. What could possibly go wrong next time?

Mike Friedman

So let me get this straight.

The cops fucked up big time. Lied about it, and then instead of facing the music, the head copper retired with full pay and benefits at FIFTY TWO?

Must be nice to never have to find out when you've fucked around and lied about it. Typical cops.

How long is it going to be before AI kills someone and the cops just shrug and say "yeah, whatever. Shit happens?"

Everyone who comes in here wants three things:
(1) They want it quick.
(2) They want it good.
(3) They want it cheap.
