That is where a suspect is compared with a database of images after a crime.<\/p>\n\n\n\n<p>Live facial recognition, which is more controversial and is used less by policing, hunts for suspects in real time, and also contains bias. A report in December&nbsp;<a href=\"https:\/\/www.theguardian.com\/technology\/2025\/dec\/05\/home-office-facial-recognition-tech-issue-black-asian-subjects\">found that a retrospective facial recognition system<\/a>&nbsp;used by police had been used with inadequate safeguards.<\/p>\n\n\n\n<p>The Association of&nbsp;<a href=\"https:\/\/www.theguardian.com\/uk\/police\">Police<\/a>&nbsp;and Crime Commissioners (APCC), which oversees local forces in England and Wales, said: \u201cSystem failures have been known for some time, yet these were not shared with those communities affected, nor with leading sector stakeholders.\u201d<\/p>\n\n\n\n<p>The APCC forensic science lead, Darryl Preston, who is the police and crime commissioner for Cambridgeshire, said: \u201cThe discovery of an in-built bias in the police national database\u2019s retrospective facial recognition system, even if only in limited circumstances, demonstrates the need for independent oversight of these powerful tools.<\/p>\n\n\n\n<p>\u201cIt is not acceptable for technology to be used unless and until it has been thoroughly tested to eliminate bias. That clearly was not the case in this instance.\u201d<\/p>\n\n\n\n<p>The new national AI centre, costing \u00a3115m, would aim to reduce bias, said Murray, as well as assessing and deciding what products from private suppliers work. Currently each of the forces across the UK makes its own decisions, which is seen as slow and wasteful.<\/p>\n\n\n\n<p>Murray said police were in an \u201carms race\u201d with criminals who were using the technology: \u201cAnyone with imagination can use AI.\u201d<\/p>\n\n\n\n<p>In one case a paedophile claimed images showing him involved in the abuse of children was a deepfake, which police then had to disprove to get him convicted.<a href=\"https:\/\/www.theguardian.com\/technology\/2026\/feb\/24\/police-ai-chief-admits-crime-fighting-tech-will-have-bias-but-vows-to-tackle-it#EmailSignup-skip-link-16\">skip past newsletter promotion<\/a><\/p>\n\n\n\n<p id=\"EmailSignup-skip-link-16\">Murray said the benefits of AI were far beyond the \u201ccliche around&nbsp;<a href=\"https:\/\/www.theguardian.com\/film\/2002\/jun\/28\/culture.reviews\">Minority Report<\/a>&nbsp;and predictive policing\u201d.<\/p>\n\n\n\n<p>He added that across a range of crimes and challenges facing policing, AI ranged from being a help to a gamechanger, but a human police officer will have to make the final decisions about what to do about the results AI produces.<\/p>\n\n\n\n<p>He said it could help police deal with political agitators who infect social media with fake images to try to trigger violence on the streets.<\/p>\n\n\n\n<p>In time, Murray said, it could help with manhunts, or speed up searches for cars linked to suspects and save the hundreds of hours it takes for detectives to trawl through extensive CCTV footage, or speed up the search of seized digital devices from suspects in the hunt for incriminating evidence.<\/p>\n\n\n\n<p>\u201cWhat took days, weeks, sometimes months can potentially take hours,\u201d he said.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.theguardian.com\/uk-news\/2026\/feb\/21\/its-not-robocop-uk-police-embrace-ai-efficiency-in-complex-investigations\">In one recent case<\/a>, four Luton-based suspects were arrested for attacks on \u2013 and thefts from \u2013 cashpoints. Police downloaded the data from the suspects\u2019 phones and, thanks to AI, secured guilty pleas within weeks.<\/p>\n\n\n\n<p>The data was in Romanian and AI scoured through it, translated it, identified the material relating to potential crimes, identified the offences and presented it all in a package for detectives.<\/p>\n\n\n\n<p>Trevor Rodenhurst, chief constable of the Bedfordshire force, told the Guardian: \u201cThis allowed us to draw evidence from lots of devices with a vast quantity of data, which we would otherwise not have been able to do.\u201d<\/p>\n\n\n\n<p>Rodenhurst said that as officers use AI and see its benefits, it is changing the view of the frontline: \u201cThey are no longer suspicious, they are asking when they can have it. That capability is transformative.\u201d<\/p>\n\n\n\n<p><a href=\"https:\/\/www.theguardian.com\/technology\/2026\/feb\/24\/police-ai-chief-admits-crime-fighting-tech-will-have-bias-but-vows-to-tackle-it\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.theguardian.com\/technology\/2026\/feb\/24\/police-ai-chief-admits-crime-fighting-tech-will-have-bias-but-vows-to-tackle-it<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Exclusive: NCA\u2019s Alex Murray says he hopes new \u00a3115m police AI centre can limit unfairness found in tools Vikram Dodd\u00a0Police and crime correspondent Tue 24 Feb 2026 07.00 GMTShare A police chief has admitted artificial intelligence used to boost crime &hellip; <a href=\"https:\/\/alanlodge.co.uk\/blog\/archives\/44940\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_seo_html_title":"","jetpack_seo_noindex":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[1],"tags":[1642,95,202],"class_list":["post-44940","post","type-post","status-publish","format-standard","hentry","category-1","tag-met","tag-police","tag-surveillance"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack-related-posts":[],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/posts\/44940","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/comments?post=44940"}],"version-history":[{"count":3,"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/posts\/44940\/revisions"}],"predecessor-version":[{"id":44943,"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/posts\/44940\/revisions\/44943"}],"wp:attachment":[{"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/media?parent=44940"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/categories?post=44940"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/alanlodge.co.uk\/blog\/wp-json\/wp\/v2\/tags?post=44940"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
