Which of the following should not be done at a crime scene to maintain integrity?

Maintaining the integrity of a crime scene is crucial for preserving evidence and ensuring the investigation remains valid. Eating or drinking at a crime scene can introduce contaminants that may compromise both physical evidence and the scene itself. Substances from food or drinks can leave residues or traces that can interfere with forensic analyses.

This practice can also distract investigators from their focus on gathering evidence and can create health concerns if any hazardous materials are present at the scene. Therefore, refraining from consuming anything at the crime scene is essential to ensure that the integrity of the evidence is preserved and legal protocols are followed.

On the other hand, adjusting thermometers, moving bodies, and actions from unauthorized personnel can also compromise a crime scene, but the specific act of eating or drinking is particularly problematic as it directly impacts the purity of evidence collected.
