Executive Summary
Smile you’re on Body Worn Camera Part II - Police reveals for the first time the investment police in
the UK have made in equipping frontline officers with body worn cameras.
Since 2010 the police, Crown Prosecution Service (CPS) and politicians have enthusiastically
promoted the roll out of body worn cameras.
The public have been told the technology is a critical tool in reducing violence against officers,
improving transparency in police/public relations, assisting the police with the number of guilty
pleas they obtain and will play an essential role in speeding up justice by being used as evidence in
court.
Off the back of such enthusiasm we felt it necessary to investigate how many police forces had
invested in the technology, how many cameras were being used by frontline staff and if the benefits
lived up to the promises promulgated by the various groups.
Responses to our Freedom of Information request reveals that 71% have adopted the technology,
with a total spend of £22,703,235 on 47,922 body worn cameras. This is a huge increase from 2010
when the police told us in response to a Freedom of Information request that they had spent
£2.2million on 2,843 cameras.
1
With such an increase in investment it would be logical to assume that the police had determined
conclusively that the technology was indispensable and worthy of such substantial spending, and
that the Crown Prosecution Service (CPS) could show the extent to which footage from body worn
cameras has benefitted conviction rates.
However, this is not the case. Neither the police nor CPS could provide us with data relating to the
use of footage in criminal proceedings. This makes it impossible to verify the promise of improved
convictions based on the use of the technology.
Furthermore, publicly available findings from the police regarding the outcome of the trials of the
technology reveal inconclusive proof of the benefits to frontline policing and the public, and ongoing
concerns with the technology itself. Meanwhile, academic research shows that the way the cameras
are deployed can impact the safety and security of the police and public alike.
If the plan for future policing is to provide every frontline officer with a body worn camera, proof of
purpose is vital. Our findings reveal that such proof is far from conclusive.
In light of our findings we make three policy recommendations:
1. Data must be collated and published to show how often body worn camera footage is
used as evidence during court proceedings and in obtaining early guilty pleas.
2. Forces must publish regular transparency reports to show how body worn cameras are
being used in day to day policing.
3. Forces should ensure that all body worn cameras deployed show clearly when the citizen
is being filmed. Protection of data when at rest or in transit must be standard.

Key Findings
Based on responses from 45 police forces
2
47,922 body worn cameras have been purchased by UK police forces.
32 Forces (71%) use body worn cameras.
4 Forces (9%) were in the process of beginning trials or were planning on rolling out
body worn cameras for the first time.
6 forces (12%) do not use body worn cameras and do not have any trials or roll outs
planned.
In total £22,703,235 has been spent on body worn cameras.
Neither the CPS nor the police told us how often footage has been used in court
proceedings.
19 forces use body worn cameras made by Reveal.
Axon (formerly trading as Taser International), supply 26,935 cameras to forces,
including the three largest police forces in England the Metropolitan Police, Greater
Manchester Police and West Midlands Police.
3 forces provided us with information relating to trials of body worn cameras which
had been undertaken.

Chapter 1: Have body worn cameras been proven to be effective?
Supporters and enthusiasts of body worn cameras say the technology will improve and enhance
transparency in frontline policing, reduce the length of time it takes to prosecute criminals, and offer
greater protection from inappropriate or violent behaviour for both police officers and members of
the public.
Senior police figures across the UK have publicly supported the roll out of the technology.
Ron Hogg, Police and Crime Commissioner for Durham Constabulary, said in 2014 The effective use
of these cameras will promote public reassurance, capture best evidence, prevent harm and deter
people from committing crime and anti-social behaviour.”
4
Whilst Andy Marsh, Chief Constable of Avon and Somerset Constabulary and the National Police
Lead for Body Worn Cameras, argued in the summer of 2016 that “When an officer wears a camera,
the evidence captured is often much higher quality. I have seen earlier admissions and quicker pleas,
together with better informed sentences and sanctions from courts.”
5
But has research into the use of body worn cameras proven these assertions to be accurate?
In 2016 the Metropolitan Police began what they described as the largest rollout of body worn
cameras by police anywhere in the world.
6
Before the roll out was approved, the Metropolitan
Police, alongside the London Mayor’s Office for Policing and Crime and the College of Policing
undertook a Home Office funded trial of body worn cameras. The trial covered the use of 500
cameras by 814 officers.
The findings of the trial
7
showed the technology had little-to-no impact on several elements of police
work. The report revealed:
no overall impact” on the “number or type of stop and searches” conducted;
no effect” on the proportion of arrests for violent crime; and
no evidence that the cameras changed the way officers dealt with either victims or
suspects.
Whilst the report identified a reduction in allegations from the public against officers when they
wore the cameras, it was noted that figures did not reach statistical significance
8
and merely
matched the overall downward trend in complaints the police were experiencing irrespective of the
use of the technology.
Despite the trial failing to provide a mandate, the Metropolitan Police proceeded to spend over
£15,000,000 on 22,000 cameras which were rolled out within the year. The rollout was greeted

enthusiastically by the then Commissioner of the Metropolitan Police, Sir Bernard Hogan-Howe, who
said their use speeds up justice, puts offenders behind bars more quickly and most importantly
protects potential victims.
9
This was said in-spite of the findings of the trial which had failed to
conclusively prove the assertions to accurately be the case.
Like the Metropolitan Police, other forces around the country have also undertaken trials and
published the findings before formally rolling out the cameras. We were sent three trial reports and
sought out others published online.
Many of the trials expressed similar concerns to the Met:
Paisley and Aberdeen Police stated that: “It is hard to demonstrate the extent of any reduction in
assaults on officers as a result of the use of BWV [body worn video] camerasand that It has not
been possible to provide evidence on whether the number of complaints against the police falls when
BWV is used.”
10
North Wales police reported that they had had “no increase in detection rates” and that “the current
effect of BWV on complaint volumes appears to be very marginal.”
11
Aberdeen and Renfrewshire police found that it had been “difficult to show a causal relationship
between the use of BWV cameras and changes in crime.”
12
Durham Constabulary suggested that it “is unlikely any impact could actually be attributed to Body
Cameras”
13
in regards to a reduction in overall crime figures.
Just like the Metropolitan Police all these forces failed to conduct further trials, choosing instead to
invest vast sums of money into a technology which was never conclusively proven to be of any real
value.
Whenever technology is to be used in policing or for public safety, trials are critical. When results are
inconclusive, the answer should be more testing not a roll-out of the technology regardless.
Whilst the police were conducting their practical trials, academics focused on researching the claims
that body worn cameras improve safety and reduce complaints of the police.
In 2014 a team of academic researchers at Cambridge University’s Institute of Criminology, in
conjunction with the Rialto Police Department in California, USA published the report The Effect of
Police Body-Worn Cameras on Use of Force and Citizens’ Complaints against the Police: A
Randomized Control Trial.

The report, known as the Rialto Study, randomly assigned body worn cameras to officers within
the Rialto Police Department for a year. During this period every interaction those officers had with
the public was recorded. The findings revealed that the use of force by officers against individuals
dropped by 59% and complaints against officers fell by 87%.
15
It is inevitable that supporters of this technology would turn to the Rialto Study as comprehensive
proof that their assumptions have been shown to be accurate. But despite the seemingly positive
outcome, the academic team consistently pointed to the fact that most of the claims made by
advocates and critics of the technology remain untested”.
16
They recommended that “police forces,
governments and researchers” should “invest further time and effort in replicating these findings”
17
and invest in further work on the subject before the use of cameras becomes widespread.
It is clear that more research is needed by both the police and academics to ensure that assumptions
do not outweigh evidence. This research should be ongoing; in addition to the collation and
publication of police forces data outlining how the technology is used on the streets and as
evidence in court.
Without conclusive proof, the claims made by senior police fall flat and the continued use of this
technology must be called into question. Moreover, if the future of policing is to increase the use of
intrusive technology, clear quantifiable evidence is needed. Having proof that the technology is
being used appropriately and is achieving the results promised is logical and crucial for transparent
and honest communication with the public.
Chapter 2: Has footage from body worn cameras been effective as
evidence in court or in securing early guilty pleas?
The Crown Prosecution Service (CPS) has also been a vocal supporter of the use of body worn
cameras, making clear that “The underlying principle of using BWV is that it can be used as
evidence.”
18
We were surprised, therefore, to discover that the CPS is unable to prove the benefits of
the technology in relation to its use in prosecutions.
One of the critical claims made by enthusiasts for the technology is that footage from the cameras
will improve sentencing and early guilty pleas.
We used Freedom of Information requests to ask both the police and the CPS how many court cases
have used footage taken from a police body worn camera which led to a successful or an
unsuccessful prosecution. We also asked the CPS how often a defendant entered a guilty plea based
on body worn camera footage and how often footage from a body worn camera was requested from
the police.
Neither the police or CPS provided us with a response.

The police cited that the data was not being centrally recorded, not being held in an easily
retrievable format or, most worrisome of all, that the data was simply not held at all. The CPS told
us that the data would require a manual review of case records.
Whilst we appreciate that systems may not have been originally established to record the use of
footage in and easily readable format, the failure to seek to build systems to record the use of
footage in a prosecution or in relation to an early guilty plea is of profound concern.
With no access to the facts and figures relating to the outcome or how footage from body worn
cameras is used it is impossible to assess the claims of their value.
If the police and CPS are insistent that the technology will improve sentencing and improve guilty
pleas they need to provide data to show the assertion to be accurate.
To the credit of the police and the CPS, we know that An Evidence Gathering Checklist
19
for the
police to use in relation to domestic abuse cases has been created. The CPS say the checklist
ensures “that all evidence is explored and everything possible is done to support victims.”
20
We welcome this approach and the emphasis on encouraging the police to consider and record the
evidence they have acquired. If it can improve prosecutions and support for victims of crime then it
is a welcome move. It also assists in the necessary analysis of police efficiency, a necessary part of
transparency. But why is such a checklist not used for all forms of criminal activity?
The police and the CPS should record when technology has been used in policing or in the building of
a case for or against an individual. The data should be stored in a readable and accessible format
and be regularly published as part of an annual review. This will allow the public to see what
benefits, if any, the technology is bringing to policing.
Chapter 3: When are body worn cameras switched on?
Police officers in the UK wearing body worn camera have discretion when the camera is on or off.
Guidance from the College of Policing and the Surveillance Camera Code of Practice make clear that
continuous, non-specific recording is not permittedand that all filming should be proportionate,
legitimate and necessary.
21
We are supportive of a discretionary on/off use of the cameras. The alternative approach of
continuous filming would excessively impinge upon the privacy of the police officers working with
the cameras, as well as the privacy of the public. However, complex issues arise in relation to
whether filming is left to officer discretion or whether it is continuous.
In the guidance to assist officers, the College of Policing guidance makes clear that the officer must
“at the start of any recording…where practicable, make a verbal announcement to indicate that the
BWV [body worn video] equipment has been activated.”
and that “If the recording has started prior

11
to the user’s arrival at the scene of an incident, they should, as soon as is practicable, announce to
those present that recording is taking place and that their actions and sounds are being recorded.
22
Taken at face value the guidance appears to be beneficial to both the officer, who will stop and
consider whether they should begin filming, and for the citizen, to clearly know when they are being
filmed.
However, research by the Institute of Criminology academics at Cambridge University (the same
team responsible for the Rialto Study) found that officer discretion and the timing of when filming
begins can lead to an increase in attacks on officers.
Working alongside UK and USA police forces, the study
23
revealed that when discretion is used rates
of assault towards officers increased by an average of 15% compared to officers not using the
cameras.
Furthermore, they pointed out that being on camera may have a detrimental impact on the
behaviour of the officer as well as the behaviour of the citizen. They make clear that being on
camera may make officers less assertive and make them more vulnerable to assault”
24
and “if an
officer decides to announce mid-interaction they are beginning to film, that could provoke a reaction
that results in use-of-force.”
25
However, the researchers considered that this could be as “officers
feel more able (or compelled) to report instances when they are assaulted”
26
, although they state
that this notion is yet un-evidenced.”
27
This research is of profound importance in highlighting the unknown impact surveillance body worn
cameras can have both on the user and on the person being filmed. Often the impact of surveillance
is only addressed in relation to privacy infringements, yet the findings of this report highlight the
psychological impact body worn cameras can have on the officer and members of the public. This
should be investigated further.
If surveillance technology worn by officers is to become a basic policing tool, the police will need to
ensure that the impact of being watched whilst at work does not impact the mental or physical
health of officers. The findings from Cambridge University must not be dismissed as issues which
will be resolved as people get used to the technology. The police must ensure that ongoing research
is undertaken into the impact on their staff using these cameras.
It will also be critical to ensure the technology officers are using is of the highest standard, and
benefits from features which clearly indicate to the public when they are being filmed.
All the cameras currently used by UK police forces feature a light which is activated when the
camera is filming. Some of the cameras have a front facing screen.

The public have been promised this technology is not about secret filming. Forces therefore should
purchase products which go to every length to emphasise when the camera is on and off and when a
citizen is being filmed.
Chapter 4: Data protection and security of footage
As with any technology that records sound and footage, the use of body worn cameras must adhere
to strict data protection laws.
Footage recorded by the cameras will likely include sensitive and personal data. Due to the
positioning of the camera incidental people may be caught on film. The interior of someone’s home
or workplace may also be captured if the camera is used during an arrest, investigation or search.
From an audio perspective names, addresses and other personal details will all be recorded.
Citizens also need to be given clarity about their data protection rights in relation to experiencing
body worn cameras. Guidance should be given on a citizen’s rights to request removal of footage or
obtain access to the footage via a subject access request. Citizens should be 100% clear that unless
criminal charges are brought, the footage of them will remain protected.
Data protection is also critical when it comes to the security of the footage on and off the device, but
the security offered by the various cameras used by UK police forces varies.
Some of the available cameras appear to take security of data very seriously. The ability to encrypt
footage held on the device offers protection should the camera be lost, stolen or hacked. Others
offer automatic deletion once data has been uploaded, minimising the volume of footage held on
the devices.
Durham Constabulary have previously raised specific concerns regarding a Veho
28
body worn
camera, pointing out that Any potential encryption of the camera is believed not to be possible due
to it being a removable SD card rather than an inbuilt memory
29
. Despite this major concern
Durham Constabulary are still using the cameras. Encrypting data is critical, but the technology must
be compatible.
We are concerned to see that the Axon cameras used by the largest police forces in the country
provide Bluetooth and Wi-Fi functions to allow officers to download or transfer footage with ease.
Both functions can be hugely insecure increasing the opportunity for the data to be intercepted,
hacked or lost.
Significant issues have also been found regarding how Axon stores their data. Sky News in August
2015 revealed some police forces were storing footage from body worn cameras on commercial
cloud servers hosted outside the UK by Taser (the manufacturers of the Axon cameras) as opposed
to holding the footage on their own systems which they had direct control over
30
.
In an age where high profile hacks and data breaches are increasingly commonplace it is easy to see
the danger of holding information in this manner. Steps must be taken to ensure that all body worn

13
cameras purchased use encryption and that the encryption isn’t subsequently undermined by poor
technological design.
There appears to be very little to justify the inclusion of Wi-Fi and Bluetooth capabilities in devices.
Officers should refrain from utilising these capabilities unless they are 100% sure the technology and
the connection is secure.
Cameras should therefore only be used if they offer a deletion-on-upload service, to ensure that no
data is left on a device longer than is necessary.
Data and security measures aside, all forces should also be confident that the technology they are
using is fit for purpose. Police reports of officers complaining about poor technology are not
uncommon.
During their trial of cameras, officers at Essex Police listed a failure to record, recording at the
wrong angle, difficulties switching it on/off and not working in poor lighting, as well as being bulky so
difficult to wear.
31
Despite this the force rolled out 411 cameras to their frontline staff at a cost of
£209,610.
Similar concerns have been raised by police in Scotland. With a recent report from the BBC quoting
officers describing the system as inoperative" and "unusable". Most worrying of all was the
reference to “one camera [which] was found by officers to be recording audio at all times even when
it was not activated to record.
32
It would be expected that such devices would be pulled immediately after such flaws were found.
There are obvious issues here which need to be addressed. Data protection should be at the heart of
the use of this technology and an important facet of this is ensuring that the public are fully aware at
all times of their rights. A failure in public knowledge in this area is a failure of the police. The actual
technology used should be of the highest quality, built with privacy, security and data protection in
mind. Poor technology leaves citizens personal data vulnerable.
Chapter 5: Oversight
Two independent bodies oversee the use of body worn cameras and video surveillance technologies:
The Surveillance Camera Commissioner (SCC), in addition to other responsibilities
33
,
oversees the use of body worn cameras by local authorities and the police.
The Information Commissioner’s Office (ICO), as part of their broader remit
34
, regulates the
processing of personal data obtained by surveillance camera systems.

th
April 2017: http://www.bbc.co.uk/news/uk-
scotland-39730665
33
The Surveillance Camera Commissioner also fulfils a wider range of responsibilities: The role of the Surveillance Camera
Commissioner is to encourage compliance with the surveillance camera code of practice. The office of the commissioner
was created under the Protection of Freedoms Act 2012 to further regulate surveillance cameras. The act required a code
of practice to be produced about surveillance camera systems. The surveillance camera code of practice sets out guidelines
for CCTV, body worn video, drones and automatic number plate recognition.
14
Both have produced their own Code of Practice
35
for the use of surveillance camera technology,
emphasising that surveillance technologies must be used only when necessary and in a
proportionate and transparent way. Body worn cameras are no exception.
Oversight is an important aspect of accountability. It must be ensured that the guidance these
bodies give is closely followed to ensure the police are using this technology correctly.
The ICO’s CCTV Code of Practice emphasises the need for ongoing scrutiny of the technology;
anyone using a body worn camera should continue to monitor the use of the BWV [body worn
video] system as a whole to see if it is still achieving its original purpose. If it appears that it is no
longer achieving this purpose or it is no longer required, you should look at potentially less privacy
intrusive methods to address the need.
36
The Surveillance Camera Commissioner makes clear that although the technology can bring benefits,
a body worn camera “is still an invasive surveillance tool and must not be used without due regard to
an individual’s privacy, the sensitive location of its use and proper recognition of legal and regulatory
guidelines.
37
There is a responsibility here on both the police and the oversight bodies. The police should closely
follow the guidance they are given by the experts, ensuring that they use this technology
appropriately in order to maintain or develop public confidence. If this is not done, then the use of
the technology should be curtailed. The oversight bodies must hold the police to account and be
frank where necessary. Collaboration is vital to ensure there is no abuse of this intrusive technology.
34
The Information Commissioner’s Office remit is broader than just oversight of surveillance cameras by organisations and
private individuals: The Information Commissioner regulates the processing of personal data as set out in the Data
Protection Act. This applies to all sectors across the UK and includes personal data that has been obtained by surveillance
camera systems. The Information Commissioner’s function includes complaints handling and enforcement powers.

Conclusion
It is inevitable that the future of policing will involve technology, but the technology used must be
shown to bring real, quantifiable and unique benefits to the police and to the fight against crime.
Our findings, alongside those of the police and academics, reveals that the promised benefits of
body worn cameras are far from proven. The findings cast doubt on the logic of a police force
spending vast sums of a waning budget on technology which they themselves have expressed
concern about.
This is not the first time that the public have been encouraged to support the use of costly
surveillance technology based on hypothetical benefits. The mass adoption of CCTV on the streets of
the UK by police and public authorities was promised to reduce crime and improve safety on the
streets. Yet after two decades and billions of pounds invested in CCTV, the reality is that it is only
effective at investigating crime after the event, not preventing it from happening in the first place.
38
Time after time CCTV is promoted based on making people “feel” safe, as opposed to ensuring they
are actually made safer.
The lessons of CCTV should be considered when it comes to deploying body worn cameras. The
public must not be led to believe that the technology is a guarantee of improved policing.
Furthermore, we must be conscious of forces deploying the technology for purposes beyond their
initial remit. Recent news reports have revealed Durham Constabulary are using the technology as a
surveillance tool to gather up-to-date images of known “villains” taken during stop and search. This
reveals the cameras are being used for a purpose far removed from the promises of senior police
that they will only be used to improve transparency, relations between the police and public and
conviction rates.
As our earlier report in this series, Smile You’re on Body Worn Camera Part 1: Local Authorities
showed, where the police lead, councils and other public authorities are always keen to follow. The
police therefore must set an example. This example should extend past best practice, and must also
make clear that it is not responsible to pursue worthless technology in the hope that after enough
time has passed the technology’s value will be either proven or forgotten about as it becomes
commonplace.
For body worn cameras to benefit both officers and society alike, the police and CPS must ensure
that quantifiable data on the use of footage and the use of the cameras is collated and published. If
the findings continue to reveal inconclusive evidence of the perceived benefits, police forces should
halt use of the technology immediately. Technology may be inevitable, but its success is not. We
should not just use technology for technology’s sake. The public should be assured that investment
in technology is value for money, and that the benefits are proven and not assumed.
38
A Home Office report concluded that the impact of CCTV had been “variable”. “Any measured change in
crime following CCTV installation could not always be attributed to CCTV”, Home Office, The impact of CCTV:
fourteen case studies, 2005, p.36
16
Recommendations
In light of our findings and based on the wide range of published research relating to the UK police
use of body worn cameras we propose a number of policy recommendations to be considered by
forces already deploying or seeking to deploy the technology:
1. Data must be collated and published to show how often body worn camera footage is used as
evidence during court proceedings and in obtaining early guilty pleas.
It is not good enough to say the evidence recorded by body worn cameras is having a positive
impact on court proceedings without proving that to be the case. It should be a matter of
further discussion regarding which organisation should be responsible for collecting and making
the information public, but both individual police forces and the Crown Prosecution Service
seem well placed to fulfil this role.
2. Forces must publish regular transparency reports to show how body worn cameras are being
used in day to day policing.
Body worn cameras have to be proven to be useful to the police both before the initial roll out
and on an ongoing basis. Regular transparency reports showing how often cameras are
triggered, what impact they are having and which situations they are useful in will help forces to
target their use of the technology more effectively. It will also help them to show why the
cameras are necessary and how they can help officers in their duties.
3. Forces should ensure that all body worn cameras deployed feature a visual aid to show clearly
when the citizen is being filmed. Protection of data when at rest or in transit must be
standard.
The increasing number of media headlines about hacks and the loss of personal data clearly
show that any form of information could potentially be at risk. The sensitive nature of the
footage captured by a body worn camera only increases this threat. To limit their susceptibility
to external threats forces have to minimise the amount of information they hold and the footage
they do retain must be properly protected.

Appendix 1: Technical Specifications
A body worn camera is a small device attached to a police officers uniform which can be manually
switched on and off. The cameras capture video and audio.
Seven different manufacturers currently supply body worn cameras to police forces in the UK. The
products are all similar but each manufacturer will offer a different capability be it size, screen
position or data protection
Reveal have provided many different cameras to police forces across the UK. Currently, their main
product is the RS2-X2.
The RS2-X2 can be worn on the chest, helmet or shoulder.
It features a front facing screen.
The camera also features a light to show when the device is recording.
Data is encrypted on the device.
Data is uploaded at the end of a shift using either the Digital Evidence Management System
(DEMS) provided by Reveal or the force’s own data storage.
Axon (formerly trading as Taser International) provide products such as the Axon Body 2 and the
Axon Flex 2.
The Axon Body 2 is a small device worn on the body.
Axon cameras do not have a front facing screen but they do feature a light which is activated
when the device is recording.
Axon provide an app to work in conjunction with the devices.
Axon cameras also feature Wi-Fi and Bluetooth functions to enable the sharing of data.
Data is encrypted on the device.
Data can be uploaded to the Axon provided cloud system.
Edesix manufactures the Videobadge series of body worn cameras.
The VB-100, VB-200 and VB-300 are rectangular and can be worn on the chest.
None of these models feature a front facing screen and only the VB-300 series features a
light show recording is in progress.
The VB-300 series is Wi-Fi enabled.
The devices feature encryption.

Appendix 3: Methodology
Beginning on the 2
nd
August 2016 a Freedom of Information request was sent to all UK police forces.
We asked each force whether or not they used body worn cameras and if this was part of a trial or a
on a permanent basis. If the force did use body worn cameras, we also asked how many cameras
had been purchased, how much had been spent, what type of cameras were being used, where the
footage was held and how long for, as well as for copies of any documentation about trials of the
technology. We also asked for details of how often footage captured by a body worn camera had
been used in court, requesting that the forces breakdown the figures between the number of
successful and unsuccessful cases.
We received 45 responses; this is equivalent to 100%. For the purposes of this report only responses
received by 1
st
April 2017 have been included.
On the 3
rd
July 2017 we sent a Freedom of Information Request to the Crown Prosecution Service.
We asked the CPS how many times they had requested and received body worn camera footage
from police forces. We also asked how many cases used the footage and the success of these cases.
In relation to this, we also requested how many times this footage led to an early guilty plea from
the defendant. Finally we asked for copies of any guidance that prosecutors have received on how to
use body worn camera footage in courts.
We received a response on 18
th
July 2017.
