How many officers are recommended to guard the crime scene of the inner perimeter?

The recommendation to have two officers guard the inner perimeter of a crime scene is grounded in the principles of maintaining security, ensuring safety, and preserving evidence. Having two officers allows for effective coverage and management of the area, ensuring that unauthorized individuals do not enter, which is crucial in preserving the integrity of the crime scene.

Two officers can work together to monitor the perimeter, communicate with each other, and efficiently control access to the scene. This level of staffing can help to prevent contamination of evidence and maintain a secure environment for investigators who will process the scene later. The presence of a single officer may not be sufficient to effectively manage access and security, while having too many officers may pose logistical challenges and could create confusion. Thus, having two provides a balanced approach to the situation, optimizing both security and operational efficiency.
