Officers in a UK police force are in favour of wearing body-worn video (BWV) cameras when attending incidents, a new study has revealed.
University of Stirling researchers were commissioned by Police Scotland to assess how BWV has been employed effectively elsewhere in Britain and globally.
The report said the force should ensure that processes are in place for effective governance and scrutiny, particularly in data handling.
The study’s leader, Professor William Webster, of the University of Stirling Management School, said: “BWV seems a simple concept – it’s a camera that police carry around – but how it’s used influences a complicated set of relationships, starting with that between the citizen and the State.
“It’s important to understand the consequences and how the technology shapes behaviour, to make sure that it is being used in the interests of society and not just in the interests of policing.
“It’s very important to establish clear protocols and training for how BWV should be used,” Professor Webster said. “For example, giving a warning and switching on when an incident is about to start.
“There also needs to be a clear plan for what happens to the recording, which is citizens’ data – is it downloaded by the officer at the end of a shift? Where to? Who can access it? What circumstances justify keeping it?
“And there must be an oversight mechanism, such as dip sampling, where random recordings are checked, possibly by lay people, to monitor how BWV is being used.
“Police Scotland commissioned this research because they want to be very careful about how they introduce emerging technologies. They have a huge opportunity in that they can learn from what other forces and countries have done well and less well.”
According to one report, Police Scotland Chief Superintendent Matt Richards said: “The chief constable has underlined his support for the wider introduction of BWV cameras in Scotland and Dame Elish Angiolini recommended our plans to expand their use be accelerated in her independent review of complaints.
“BWV requires significant investment but has the potential to enhance the vital bond of trust and confidence policing in Scotland has with our fellow citizens and which underpins our legitimacy. BWV can also lead to swifter justice outcomes.
“We agree a wider roll-out of BWV must be ethical and transparent and we are encouraged that our previous national public consultation in 2021 found overwhelming support for its introduction. The feedback we received will help inform our BWV Code of Practice. We are also taking advice and guidance on ethical, human rights and civil liberties considerations.
“We are grateful to Professor Webster for this work which adds value to our thinking and approach.”
Researchers carried out a literature review of existing material and questioned 11 senior policymakers and practitioners in the field, including Scotland’s Biometrics Commissioner.
Professor Webster said: “The police like BWV because it offers them protection during risky encounters, de-escalating violence, for example, and collects evidence for prosecutions. But it also puts the police under surveillance. For instance, elsewhere, it has picked up officers smoking on duty, or using a mobile phone when driving, so that has to be considered.
“Then there needs to be further thought about usage during sensitive circumstances, such as at a mosque, or when responding to domestic violence. Trust in technologies and in the police can easily be lost.”
Martyn Evans, Chairman of the Scottish Police Authority, said: “The use of BWV is widespread across UK policing and there is good evidence of the positive benefits to both public interest and effective policing.
“The authority supports its wider roll-out in Scotland as a matter of priority. As with all technologies, the appropriate checks and balances will need to be in place to ensure data protection and privacy concerns are considered fully and managed carefully. This research reports some of the key assurances and training protocols that the authority would expect to be provided in the roll-out of BWV.”
Professor Webster added: “Practitioners such as the police are usually not in a position to accumulate all the knowledge they need, so it’s really important they work with academics who can do so, so that they introduce technologies in an accountable way that serves the interests of the public.”
