Why is it important to handle evidence with care?

Handling evidence with care is essential primarily to preserve its integrity and prevent damage or contamination. When evidence is collected from a crime scene, it may contain crucial information that can directly impact the outcome of an investigation or court case. Any mishandling, such as physical deterioration, contamination by foreign substances, or even changes in the evidence's condition, can compromise its reliability and the conclusions drawn from it.

For instance, biological evidence can degrade if not stored at the appropriate temperature, while trace evidence can be lost through mishandling. Proper techniques, such as using gloves, appropriate packaging, and maintaining a secure chain of custody, all serve to maintain the evidence in a state that is both reliable and admissible in court. Preserving the evidence's original state is critical for forensic analysis and for providing proper support during legal proceedings.
