Connecting Research in Security to Practice (CRISP) reports provide insights into how different types of security issues can be tackled effectively. Drawing on research and evidence from around the world, each report summarizes the prevailing knowledge about a specific aspect of security, and then recommends proven approaches to counter the threat. Connecting scientific research with existing security actions helps form good practices. Reports are written to appeal to security practitioners in different types of organizations and at different levels. Readers will inevitably adapt what is presented to meet their own requirements. They will also consider how they can integrate the recommended actions with existing or planned programs in their organizations.This CRISP report invites retailers to take a critical look at their handling of Organized Retail Crime (ORC). Chris Richardson and Walter Palmer combine their extensive experience of advising retailers on how to manage security risks with a very helpful summary of previous research, to stimulate thinking on how best to respond to ORC. Their starting point is that retailers and any others involved need to be clear about the type of ORC problem they are facing and its drivers, as well as the types of measures that are already in place that can be marshalled as part of an overall approach to making a response effective. They unpick the merits and limits of different types of security and offer a number of frameworks to guide practitioners. In so doing it is likely that this paper will become one of the essential reference points for those who need to tackle the ORC threat.
