What are the 8 Principles of Excellent Investigation?

Good investigations are based on eight fundamental principles.

  1. Investigators must be as independent as possible.
  2. Investigators must be trained and experienced.
  3. All potentially relevant issues must be identified and, where appropriate, pursued.
  4. Investigations must be sufficiently resourced.
  5. All relevant physical and digital evidence must be identified, preserved, collected and examined as necessary.
  6. All relevant documentation must be secured and reviewed.
  7. All relevant witnesses must be identified, segregated where practical and thoroughly interviewed.
  8. The analysis of all the material gathered during the investigation must be objective and based solely on the facts.
