Police in the UK face criticism for using live facial recognition at the Carnival

Concerns Surrounding Live Facial Recognition at Notting Hill Carnival

The Metropolitan Police have been working on enhancing their live facial recognition technology for almost ten years now. Recent large gatherings, like the Notting Hill Festival in West London, have served as key test cases for this tech.

However, there’s a growing chorus of dissent against this surveillance approach. Various groups are advocating for a reevaluation of the technology, citing its proven limitations and questioning its legal validity.

One sentiment expressed is that while there’s a collective desire to keep criminals off the streets, transforming cultural celebrations into extensive police lineups isn’t the solution.

In a letter to the Metropolitan Police, 11 organizations including Big Brother Watch and Human Rights Watch, urged a halt to the use of such technology. Commissioner Mark Lowry remarked that it poses significant surveillance risks, treating all carnival-goers as suspects, which feels inappropriate in the midst of one of London’s main cultural events.

Since 2016, live facial recognition has been utilized at the Notting Hill Carnival. According to reports, this technology involves matching faces captured by police camera systems to existing police records. The police assert that this enables them to identify potential suspects quickly, especially in crowded areas.

Laurie acknowledged the early-stage limitations of the technology but claimed substantial progress has since been made. However, critics point out that the event is meant to celebrate the African and Caribbean communities within the UK, yet the choice to implement technology known for its inaccuracies and racial bias raises concerns.

Rebecca Vincent, an interim director at Big Brother Watch, shared her belief that turning festive occasions into large police lineups isn’t the answer to public safety.

Reports suggest that since January 2025, this technology has led to 457 arrests, albeit with seven instances of wrongful identification. While the police tout advances in facial recognition technology, advocates emphasize the negative impact it has on law-abiding citizens. One case highlights a Black Londoner, Shawn Thompson, who was mistakenly identified as a suspect and detained for about half an hour after leaving work, which he described as a humiliating experience.

In defense of its “doubling” of facial recognition use, Commissioner Laurie argued that it’s necessary to tackle potential issues at public events. He asserted that the technology could aid in identifying individuals posing safety risks.

Plans are underway to expand the use of facial recognition vans into regions like Greater Manchester and West Yorkshire, with some already operational in areas like South Wales and Essex.
