MCOLES State Licensing Practice Exam

What is the very first action you should take when conducting an initial investigation at a crime in progress?

1. Establish control of the perimeter

2. Gather evidence from the scene

3. Interview potential witnesses

4. Call for additional backup

The correct answer is: Establish control of the perimeter

Establishing control of the perimeter is essential when conducting an initial investigation at a crime in progress. This action is crucial for multiple reasons. First, it ensures the safety of both the officers on the scene and any bystanders, as securing the area prevents further escalation of the situation or the potential for escape by suspects. By controlling the perimeter, law enforcement can minimize the risk of evidence being tampered with and manage the scene effectively. Furthermore, when the perimeter is secured, it becomes easier to identify all individuals present at the scene, including possible witnesses and suspects. This first step enables officers to maintain order and focus on the critical aspects of the investigation, such as assessing the situation and determining if immediate action needs to be taken to apprehend a suspect or assist victims. Gathering evidence, interviewing witnesses, or calling for backup are important subsequent actions, but they rely on the foundation of a secure environment. Without first establishing control, these activities may be compromised and could lead to confusion or danger during the investigation.
