The book covers a broad variety of applied topics including decision making, eyewitness testimony, suspect interviewing, behavioural investigative advice and the nuances involved in assessment and treatment of offenders. Considering seminal research alongside more recent empirical evidence, the book also considers the various research methods used - from utilisation of vast databases to interviews gleaning in-depth, first-hand knowledge from those involved. Importantly the authors explain how this topic overlaps with other fields such as criminology and law and discuss examples of its wider impact on policy and practice. Finally, the authors consider key emerging areas, such as new crime threats, and suggest new directions for research.
