JST226 Introduction to Police Investigations (8)

This subject will provide those students who intend seeking a career in a police service with a fundamental understanding of the investigative processes carried out by police. The central theme throughout is the application of those ethical and legal principles which impact on investigation practice. Investigation processes are examined with reference to logic, critical thinking and scientific method. Sources of information available to police are canvassed, with the final focus being on investigation and interviewing as evidence. Specific reference will be made to the P.E.A.C.E. model of investigative interviewing. The theoretical component is applied to investigation practice.
