The reliability of CCTV images as forensic evidence

Abstract

Forensic evidence originating from CCTV images is admitted as evidence into various criminal courts in Australia and overseas. It is used predominately to identify persons of interest from images captured by CCTV cameras but other forms of forensic evidence and intelligence are also possible. Using a mixed method research design, this study examines the reliability of CCTV images when used as forensic evidence. A range of strategies including case studies, empirical experimentation and phenomenological inquiry is used to investigate the application of this new form of evidence. Understanding the reliability of evidence derived from photographic sources requires a highly complex interdisciplinary and multifaceted approach. This study has found serious reliability problems with the current use of CCTV images when used as forensic evidence. Serious miscarriages of justice are inevitable if the reliability of photographic evidence practices are not more carefully considered and validated. The study argues that reliability will be improved by establishing more robust methods that enhance the scientific model of repeatability and validation. Thisstudy also establishes a new theoretical model that examines the application and relationship between photographic evidence and physical evidence. Furthermore, the work develops a method for more reliable photointerpretation. The study also recommends that the principles cited in the Daubert ruling be considered for photographic evidence to provide safeguards and improve the reliability of this new form of forensic evidence.
