Carnival Faces Pressure to Abandon Facial Recognition Plan

Civil Liberty Groups Oppose Use of Facial Recognition at Notting Hill Carnival

Civil liberty and anti-racism organizations have raised concerns about the Metropolitan Police's plan to implement live facial recognition (LFR) technology during this year's Notting Hill Carnival. These groups argue that the use of such technology is inappropriate for an event that celebrates cultural diversity and could lead to mass surveillance.

In a letter addressed to Met Commissioner Sir Mark Rowley, 11 organizations expressed their disappointment with the decision to reintroduce LFR at the carnival. They described the technology as a "mass surveillance tool" that treats all attendees as potential suspects. The letter emphasized that the carnival is a significant cultural celebration in London, and the use of LFR does not align with its values.

The groups highlighted the potential inaccuracies of LFR, particularly for women and people of color. They pointed out that there is currently no specific legal framework governing the use of facial recognition technology in the UK. The absence of parliamentary scrutiny over its deployment has raised further concerns among the organizations.

One of the key issues raised in the letter is the case of Shaun Thompson, a black Londoner who claims he was wrongly identified by the system and detained. This incident underscores the broader concerns about the reliability and fairness of facial recognition technology.

A 2023 study conducted by the National Physical Laboratory found that the NeoFace system used by the Metropolitan Police showed lower accuracy rates for women and individuals of color, depending on the algorithm settings. However, the Met Police maintains that the system is accurate and balanced when using higher confidence thresholds, which are less prone to bias.

Despite these claims, campaigners argue that there is no legal requirement for the police to avoid lower thresholds, which could result in more errors and biased outcomes. They suggest that resources should be directed towards other safety measures rather than relying on LFR technology.

Deputy Assistant Commissioner Matt Ward, who is overseeing this year's policing efforts, stated that LFR has led to over 1,000 arrests since the start of 2024. He cited independent testing that supports the system's accuracy and balance regarding ethnicity and gender. Ward also emphasized the importance of keeping attendees safe, especially in light of previous incidents of violence at the event.

The Notting Hill Carnival, which attracts up to two million people, has faced increased scrutiny following two murders at last year's event. Ward noted that around 7,000 officers and staff will be deployed each day to ensure public safety. He explained that LFR cameras will be used on the approach to and from the carnival, not within the event boundaries, to identify and intercept individuals posing a public safety risk before they reach crowded areas.

The Metropolitan Police has received the letter from the civil liberty groups and plans to respond in due course. The ongoing debate highlights the tension between technological advancements in law enforcement and the need to protect civil liberties and prevent racial bias.

As the carnival approaches, the discussion surrounding the use of facial recognition technology continues to spark debate. While the police emphasize the benefits of LFR in enhancing public safety, civil liberty advocates remain concerned about its potential impact on marginalized communities.

Organizers of the Notting Hill Carnival have not yet commented on the issue, and the final outcome of the debate remains uncertain. The situation reflects a broader conversation about the role of technology in policing and the balance between security and individual rights.
