What should officers do if they see potential evidence at a crime scene?

The correct approach when officers see potential evidence at a crime scene is to photograph and document it without moving it. This method preserves the integrity of the evidence and maintains a clear record of how it was found in its original context. Photographing the evidence first allows investigators to capture details about the evidence's relationship to the surrounding scene, which can be crucial during the investigation and presentation in court. Documentation can include detailed notes about the location, condition, and any other relevant observations.

Moving or touching potential evidence can lead to contamination or destruction of important forensic information. Each piece of evidence could hold critical clues that are essential for solving a case, and altering its position can hinder the investigation. Additionally, discarding evidence disregards its potential significance altogether. Therefore, careful documentation is vital for maintaining a complete and accurate portrayal of the scene.
