Body-worn video cameras were presented as a transformative accountability tool when forces began rolling them out from 2012 onward. The College of Policing’s guidance promised better evidence quality, reduced complaints, and improved officer behaviour. Over a decade on, FOI requests submitted by Exposed News to all 43 territorial constabularies reveal a more complicated picture.
The FOI Requests and Responses
Exposed News submitted identical FOI requests to all 43 forces asking for: the total number of body-worn cameras deployed; the percentage of patrol shifts where cameras were worn by all officers; the number of formal complaints made about failure to activate cameras; and the force’s data retention period for footage.
Thirty-one forces responded in full or in part. Eight forces declined to provide deployment statistics on the grounds that this information was exempt under Section 31 of the Freedom of Information Act (law enforcement exemption), arguing that camera deployment data could assist those seeking to evade police. Three forces did not respond within the statutory 20 working day period and did not respond to follow-up requests. One force said it did not hold the data in a retrievable format.
The Section 31 exemptions were contested internally. Legal commentators consulted by Exposed News considered the exemption unlikely to withstand an Information Commissioner’s Office challenge in most cases: camera deployment figures are aggregate statistics that do not reveal specific patrol locations or times.
Deployment and Activation Gaps
Among the 31 responding forces, deployment rates varied from 94% of patrol officers equipped with cameras (three forces) to 67% (one force). Two forces acknowledged that they could not reliably measure whether cameras were activated during all incidents where policy required activation, because their camera management systems did not automatically flag non-activation.
Activation policy is a significant variable. Most forces operate a “record by exception” policy — officers are expected to activate cameras when attending incidents but are not required to record all interactions. Critics argue this creates a gap in accountability precisely in the situations where footage would be most valuable: low-level interactions that are not categorised as “incidents” in advance but which can escalate.
A minority of forces — six in the responding sample — have moved toward a “default on” policy for specific categories of deployment, including stop and search, arrest, and use of force. Of these, four reported measurable reductions in complaints about officer conduct following implementation.
Retention and Access
Retention periods varied from 30 days to 12 months for footage without evidential value. Forces with shorter retention periods — 30 days was the most common — mean that footage relating to incidents that are later the subject of complaints may no longer exist when the complaint is investigated, if the complaint is made more than a month after the event.
The College of Policing guidance recommends a minimum retention period of 31 days, extendable where footage may be relevant to ongoing proceedings. Several forces were retaining footage for the minimum period without the extension protocol being reliably triggered when complaints were made.
Access to footage by members of the public who have been recorded is a formal right under UK GDPR, subject to law enforcement exemptions. FOI responses indicated that seven forces had received formal subject access requests for body camera footage that they were unable to fulfil because the footage had been deleted within the retention period — after the complaint had been registered but before the request was processed.
What the Gaps Mean
Body cameras can only serve as an accountability tool if footage exists and is accessible when accountability is sought. The data suggests three systemic weaknesses: inconsistent activation during interactions that turn out to be significant; retention periods too short to support complaints made weeks after an incident; and data management systems that do not reliably flag footage as evidence-relevant when a complaint is made.
The College of Policing updated its body-worn video guidance in 2023. It does not mandate activation policy, retention periods beyond the minimum, or specific technical standards for flagging. Several forces told Exposed News they were operating under locally-developed policies because national guidance left significant discretion to individual constabularies.
The IOPC told Exposed News that body-worn video evidence was “central to a significant proportion of our investigations” and that footage gaps were a known challenge: “We have raised retention and activation consistency with forces as part of our learning recommendations. This remains an area requiring continued attention.”
