This week’s blog is written by UWE Bristol Policing programme Senior Lecturer Gary Stephens. Gary served in Avon & Somerset Police as a Detective Chief Inspector prior to joining UWE Bristol where he is the module leader for ‘Becoming an Evidence-based Police Practitioner’ on the Police Constable Degree Apprenticeship (PCDA).

There is general consensus that Evidence-based Policing (EBP) is the development of knowledge, which is shared to inform operational practice. Working together with Avon & Somerset Police we seek to blend the best of policing craft with the science of ‘what works’. This is important because traditional models of policing no longer appear to provide the answers to a lot of current and future policing problems. Having recently attended the Society of Evidence Based Policing (SEBP) annual conference, Gary reflects on the key learning from this event.
Society of Evidence Based Policing (SEBP) annual conference
Over the 9 – 10 November, the SEBP held their annual conference at the College of Policing in Ryton. The SEBP are insiders, they are predominantly police officers with day jobs who are committed to nurturing change from within their organisation by developing knowledge, practice and performance utilising Evidence Based Policing.
Attending the conference were UWE policing staff Associate Director Dr Anne Eason along with Senior Lecturer Gary Stephens. Amongst the over 130 other candidates were representatives from forces and organisations from around the country, and internationally, including Inspector Alecto Shyne and PS Sue Coates from the Avon and Somerset Inspection and Evidence Based Policing Team.
The title of the conference was:
The importance of focus: How can evidence based policing drive precision policing?

The conference was opened by the SEBP Chair T/Chief Constable Alex Murray of West Mercia Police who introduced the variety of speakers delivering presentations over the two days. A consistent theme was the importance of modern policing being data led and optimising the principle of ‘what works’.
The College of Policing are at the forefront in using evidence led policing and Director of Knowledge and Innovation Rachel Tuffin outlined recent developments, most notably the practice bank, which complements the longer standing Crime Reduction Toolkit. The practice bank shares crime prevention and community safety best practice initiatives developed across the country to assist officers in their own local problem solving.
Speakers spoke of subjects ranging from crime satisfaction, focused deterrence to using vetting data to understand the more prevalent characteristics of those who go onto be subject of gross misconduct proceedings. Whilst there was a wide range of speakers there was one consistent theme, the importance of using data to produce a deeper understanding of what works and to utilise this as evidence to inform practice.
So what did we take specifically from the two days?

The material from all speakers was valuable but what we found most interesting is how EBP is constantly developing and how we can all contribute to it. For example, we now know that, under certain conditions, hot spots policing works. One of these conditions is optimising the time officers (or PCSOs) are present in a given hot spot (The Koper curve theory). However, a study in Leicester based on hot spot patrolling areas of potential disorder has developed this principle further. In partnership with the Youth Endowment Fund youth outreach workers were employed to be in hot spot areas and engage with youths to prevent disorder. During this time they sought to engage those youths in diversionary interventions, something EBP tells us works. But to follow Koper’s 12-16 minute rule would not enable them to engage, so the patrols were extended, often in excess of 50 minutes, which allowed them to nurture conversations and engage with potential offenders.
The conference was closed by Professor Lawrence Sherman, the leading architect and proponent of EBP who outlined the need to move from the 3R’s (random patrol, rapid response, reactive investigation) toward the 3Ts (targeting, testing and tracking). As well as reflecting on where EBP was and where it is now he outlined his vision of the next steps for it. As Chief Scientific Officer for the Metropolitan Police he took an active role in an initiative that was recently launched to target the serious amount of violent harm against women and girls in London. With limited resources the police must focus their resources on those who present the most harm. A top 100 list, ‘the power few concentration’ was produced. Having identified the top 100, a key tactic used was application for Sexual Risk Orders. If the application is successful, this order places stringent conditions on subjects. In the short time since this initiative has been running an impressive 85% reduction in offending has been identified.

Professor Sherman suggested that future steps for EBP could be in adopting these principles of ranking and stacking relative risk, and further utilising the principle of the 3T’s, in categories such as repeat burglary, ASB 999 calls, police misconduct and others. If adopted this could lead to what he described as not doing more with less, somewhere policing has found itself in recent years, but doing less with more.
What can you do?
- Join the SEBP, it’s easy, just go online and join. You will receive regular e mails of evidence-led studies and initiatives and you will have access to all resources.
- Look out for the posters around campus with QR codes you can click on to provide direct access to the practice bank amongst other resources.
- Be that evidence led practitioner – it works! As a practitioner guided by evidence, integrate its effectiveness seamlessly into your daily operations for your specific purposes. Embrace the principles, customise them to your context, and employ them to focus on your objectives. Shift from perceiving it as an abstract concept; it’s increasingly becoming standard practice, and we need to fully harness the principles of EBP in contemporary law enforcement.
