Before entering a building or protected area, what should an officer do first?

The correct course of action for an officer before entering a building or protected area is to assess the perimeter from a distance. This step is crucial as it allows the officer to observe the surroundings and identify any potential threats or suspicious activities without putting themselves in immediate danger. By maintaining a safe distance, the officer can gather valuable information about the situation, including the presence of individuals, possible escape routes, and any environmental factors that could affect their approach.

Assessing the perimeter aids in formulating a tactical plan for entering the building. It allows the officer to consider various factors such as sightlines, cover, and potential entry points, which are essential for ensuring their safety and the safety of others involved. This strategic approach is vital in law enforcement situations where quick decision-making and situational awareness can have significant implications for the outcome of the encounter.

While inspecting the interior for threats and securing the building's entrance are important actions, they should only be undertaken after a thorough assessment of the perimeter has been made. Calling for backup may be necessary if the assessment reveals potential risks, but doing so without first evaluating the situation could lead to unnecessary complications or delays.

Overall, the priority is to gather as much information as possible about the situation outside the building before taking any further action
