Importance of Establishing Identity in Factual Investigations
Investigations are part of daily routine, in every aspect of life and there is no certain moment in history which we can use as a starting point to define investigation, however investigations are improving, implementing and evolving since the dawn of humankind.
Our ancestors certainly used intuition and some type of skills to make conclusion about events, how to gain competitive edge or to win over their opponents. They also used some form of evidence or facts. Since then investigation methodology and tactics have evolved immensely, to a scale that ordinary people can only imagine.
Investigation doctrine is not the classic scene where a detective smashes a suspect on the head to get them to admit guilt. It has evolved with the legal and judiciary system by protecting the individual from an abuse of their legal rights.
