What is a key aspect of assessing the perimeter in a scene?

Assessing the perimeter of a scene is crucial for ensuring officer safety and maintaining control of the situation. When waiting for backup, officers can gather intelligence, observe the scene for any suspicious activity, and maintain a safe distance while the perimeter is being established. This step is essential because entering a scene without adequate support can expose officers to unnecessary risks, particularly in potentially volatile situations.

By waiting for backup, officers can effectively plan their approach, coordinate efforts, and prepare for any challenges that may arise. This allows for a more thorough and secure perimeter assessment, making it easier to monitor the situation and respond to any developments safely. The safety afforded by this approach is a primary reason it's considered a key aspect of perimeter assessment.

Other choices, like making entry, checking for alarms, or circuiting the area, involve more direct engagement with the scene, which can increase risk and may not adequately prioritize safety before taking further action.
