What is the process of collecting and analyzing physical evidence at a crime scene referred to as?

The process of collecting and analyzing physical evidence at a crime scene is best referred to as crime scene investigation (CSI). This term encompasses the overall approach and methodology used to understand the events that occurred at a crime scene through the examination of physical evidence. In CSI, trained professionals follow specific protocols to ensure that all evidence is accurately collected, preserved, and documented.

This process includes not only the physical gathering of items and samples but also the systematic analysis, which may involve various forensic techniques. Through forensic science, investigators can interpret the evidence collected, which is essential for building cases and uncovering the truth behind criminal activities.

Other choices, while related, do not capture the comprehensive nature of the investigation process as effectively as crime scene investigation. Forensic analysis typically refers to the scientific techniques used to analyze the evidence after it has been collected. Evidence collection focuses on the actual act of gathering materials from the crime scene, and legal documentation pertains to the recording of findings and procedures for legal purposes. Each of these elements is a part of CSI but does not represent the entire process.
