JST311 Evidence and Investigation (8)

This subject considers the process of transforming information into the stipulative reality known as evidence. Using recent case studies and court decisions from a number of differing jurisdictions, the subject examines in detail the ethical and legal complexities of the gathering and presenting evidence. The student is 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 the facts in an investigation, both inculpatory and exculpatory.
