ABSTRACT
This chapter introduces the concepts of evidence-based investigation, along with crime prevention and reduction (such as controlling access through barriers at entry points or physical surveillance through technology). It commences with an overview and historical context, referring to specific examples of investigations to support the discussion and give a context. The chapter compares investigation methods in use in the 1970s with those of today. It refers to the models of Problem Oriented Policing, which originated in the USA, the National Intelligence Model, and the Professionalising Investigation Programme process, showing how its use has expanded in recent years from that of interviewing to that of the wider investigative process. Specific advances in the detection of crime are referred to, such as the use of DNA as a means of identification, the benefits of Closed Circuit Television Cameras (CCTV) and Automatic Number Plate Recognition (ANPR) Cameras.
