Evidence handling refers to the systematic process of collecting, preserving, and documenting physical evidence from a crime scene or incident. This process ensures that the evidence remains intact and uncontaminated, which is crucial for maintaining its integrity in legal proceedings. Proper evidence handling includes using gloves, appropriate containers, and clear labeling to track the chain of custody. The chain of custody is a critical aspect of evidence handling, as it records every person who has handled the evidence from the moment it is collected until it is presented in court. This documentation helps establish the authenticity and reliability of the evidence, which can significantly impact the outcome of a case involving law enforcement, criminal justice, or forensic science.
