New approaches to reducing crime

16 December 2014

Crime prevention research at UCL has helped to shape policy and policing practice in the UK and internationally. Working closely with police forces, crime prevention practitioners and policymakers, staff at UCL Security & Crime Science (SCS) provide evidence, expertise and advice to support particular crime prevention initiatives and approaches to crime prevention more broadly.

Policing and broader criminal justice responses to crime have traditionally focused on catching offenders after an offence, and administering punishments to deter future offending. In contrast, UCL SCS focuses on identifying the situational factors that enable or encourage specific crime problems, devising means of reducing opportunities and incentives to crime, and analysing how effective these strategies are. For example, a collaboration with Warwickshire Police and Warwickshire Council found that introducing a new trolley design was successful in reducing bag and purse theft in supermarkets.

Professor Nick Tilley is a leading authority on the delivery of situational crime prevention through problem-oriented policing, which has strongly influenced crime prevention policies in the UK. Researchers from UCL SCS have presented to House of Commons select committees to argue for the greater use of situational crime prevention. Since 2011, Professor Richard Wortley has contributed to a Home Office Forum for Innovation in Crime Prevention, which helps shape government policy in this area.

UCL SCS staff have also worked directly with police forces and crime prevention agencies around the world. For example, they have delivered specialist training to the New Zealand Police, which credits UCL SCS with a significant role in developing crime science and intelligence-led policing in New Zealand.

Two examples of this type of prevention in action including reducing bike theft and internal child sex trafficking in the UK.

The British Crime Survey for 2010-11 indicates that around half a million bicycles are stolen every year. A collaboration between Professor Shane Johnson and designers from Central St Martin's College of Art and Design found that 'n'-shaped bike stands did not encourage good locking practices, with 70% of bicycles inadequately secured. UCL SCS studies recommended installing the 'm'-shaped CaMden stand, a new type of bike stand that encourages cyclists to secure the wheels and frame of their bike. More than 1,200 have since been rolled out nationally. Professor Johnson and colleagues wrote a guide for the US Department of Justice, which then led to work with Transport for London (TfL) and the London Metropolitan Police Service to cut cycle theft. TfL reports the project achieved a 5.4% decrease in cycle thefts in London during 2010-11.

UCL SCS research shows that those who sexually offend against children are strongly influenced by situational factors. The work examined the social networks of offenders and victims to map connections that support the abuse and that might be able to be disrupted. For example, one case identified an offender network built around a central ringleader and argued that targeting this individual might dissolve the network. Another study developed a detailed breakdown of the steps involved in internal child sex trafficking, designed to identify 'pinch points' for prevention. For instance, identifying strategies employed by offenders to locate and groom girls for abuse enabled the development of advice for potential victims on self-protections strategies. 

Largely due to increased media coverage, internal child sex trafficking has, in recent years, been widely recognised in the UK as a pressing public issue. UCL SCS research has challenged the perception, dominating public debate, that internal sex trafficking is a racially motivated crime. Through contributions to the development of a lively debate, the the research has also influenced the formulation of national policies on tackling this issue, including reports by the Child Exploitation and Online Protection Centre, the Metropolitan Police Authority and the Department of Education.
