Which of the following describes a fundamental crime scene procedure?

Limiting the number of personnel present at a crime scene is a fundamental procedure for several important reasons. Keeping the number of people who have access to the scene as low as possible helps to preserve the integrity of the evidence. Each individual who enters the crime scene has the potential to disturb or alter the evidence, whether intentionally or unintentionally. This is vital for ensuring that the evidence collected is reliable and can be used effectively during an investigation or in court.

Additionally, fewer personnel on-site facilitates better communication and coordination among those who are authorized to gather information and handle evidence. This reduces the risk of contamination or loss of crucial investigative details, ensuring that the crime scene remains secure for analysis by trained professionals.

In contrast, establishing headquarters near the scene may be helpful for managing the investigation but does not directly affect the preservation of the scene itself. Publicly disclosing all details immediately can compromise the investigation and lead to misinformation. Regularly cleaning the crime scene is not standard procedure, as it can remove vital evidence rather than maintain order. Therefore, limiting personnel is the most critical step for preserving the scene and supporting the integrity of the investigation.
