JST311 Evidence and Investigation (8)

This subject considers the process of identifying, recovering and presenting evidence obtained in the course of investigations. Using recent case studies and court decisions from a number of different jurisdictions, the subject examines in detail the ethical and legal complexities surrounding the gathering and presenting of evidence. Students are challenged to ensure that evidence is gathered in a manner which avoids common pitfalls often experienced by investigators. Emphasis is placed on the need to locate all facts in an investigation, both inculpatory and exculpatory. The subject also explores management processes that ensure an ethical investigation is carried out, and the ethical actions of those involved in all stages of the investigation.
