Policing in the era of overwhelming video data
Privacy in Policing is a constant, growing concern. The role of video cameras in law enforcement - such as CCTV, BWCs (body-worn cameras), doorbell cameras, and drones - has become increasingly pivotal in evidence gathering.
Despite a £1.4 billion investment in technology in 2018, issues of data mishandling persist. A 2023 BBC investigation cited over 150 incidents - including officers tampering with cameras and sharing footage irresponsibly.
It is clear that there is a growing need for updated guidelines, stricter compliance measures, and enhanced training. The National Police Chiefs’ Council's 2022 update to Body-worn video guidance aimed to addresses these concerns, yet more comprehensive measures are necessary.
The main challenge lies in balancing thorough investigations with the protection of individual privacy.
The National Policing Digital Strategy 2020-2030 emphasises the need to modernise data and technology to address organisational structures, underinvestment, risk aversion, and inconsistent data understanding.
A policy shift for tackling crime
Concurrently, after years of austerity, UK police forces have had to prioritise high-harm cases, leading to a neglect of less severe crimes. This approach has resulted in a decline in public trust, as evidenced by low conviction rates in cases of vehicle theft, minor assaults, criminal damage, and home burglaries.
A recent policy shift now demands that all evidence, especially video data, be given due diligence in every crime report with a reasonable lead.It aims to rebuild public trust, increase conviction rates, and deter crime.
However, it also intensifies the workload on police resources and necessitates stringent adherence to data protection laws. UK police forces employ various systems for managing video evidence, including BWC footage, Digital Evidence Management Systems (DEMS), and forensic platforms. Yet, challenges such as backlogs in device examination and variability in service delivery still need to be addressed.
A 2022 report by His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) recommends an alternative operating model for digital forensic services, a national digital forensics policing lead, budget review, and increased training for digital media investigators.
Leveraging AI for visual data management
Integrating AI in policing is revolutionising the management of overwhelming video data.
AI technologies offer an efficient solution to store, manage, and redact large volumes of footage from various sources like body-worn cameras and CCTV whilst ensuring adherence to privacy standards.
These systems can automate time-consuming tasks like scanning and analysing video data, identifying pertinent segments, and redacting sensitive information. This enhances the efficiency and effectiveness of police investigations.
However, the successful deployment of AI in police forces demands careful consideration of operational challenges. This involves addressing potential risks such as biases in algorithms and errors in data interpretation through established guidelines and oversight.
Additionally, comprehensive training for law enforcement personnel is essential to navigate AI usage's operational and ethical aspects. With automated data management processes, AI not only increases operational efficiency but also enhances accountability, which reduces opportunities for data mishandling and increases transparency in police work.
As law enforcement navigates this new frontier, the balance increased data with privacy compliance and resource management becomes crucial. Modern software solutions, like Secure Redact, provide tools for efficient, privacy-compliant video data management. These tools are vital for police forces to adapt to the digital age and ensure justice delivery while respecting privacy and data protection laws.
