What is the function of evidence in an investigation?

The function of evidence in an investigation is fundamentally to ascertain or give proof of a fact. Evidence serves as the backbone of an investigation, allowing investigators to establish what occurred during an incident. It is essential for building a case, as it provides the necessary substantiation to support claims and conclusions drawn by law enforcement officers.

In judicial proceedings, the strength and credibility of evidence can directly influence the outcome of a case, including the decisions made by prosecutors in pursuing charges or a jury in determining guilt or innocence. Properly collected and documented evidence can lead to definitive conclusions about the facts of the case, thus driving the entire investigative process. Understanding the role of evidence in establishing facts is crucial for any professional involved in law enforcement, particularly in the capacity of a Master-at-Arms, where securing and presenting evidence is a fundamental duty.
