The primary goal of forensic science lies in determining the evidential value of the crime scene. Forensic science involves the application of scientific principles and techniques to collect, preserve, and analyze physical evidence from crime scenes. This process is crucial for establishing facts that can support or refute claims made in legal investigations.

In a forensic investigation, high-quality evidence is essential to ascertain what happened during an incident, who was involved, and sometimes even how it occurred. By scrutinizing the crime scene and applying various scientific methods—such as DNA analysis, fingerprint matching, ballistic analysis, and digital forensics—experts aim to gather reliable data that can be utilized in court.

Understanding the evidential value of a crime scene not only aids in identifying the perpetrator but also serves the justice system by ensuring that legal proceedings are based on factual and analyzed information. Other aspects, like mitigating security breaches or preserving the goodwill of organizations, are important but secondary to the fundamental forensic objective of collecting and evaluating evidence.
