Which of the following should be included in initial response objectives?

Conducting a scene size-up is a critical objective during the initial response to an incident. This process involves assessing the situation to ensure the safety of all individuals involved, including law enforcement personnel, victims, and bystanders. A thorough size-up allows officers to gather information about the nature of the incident, identify potential hazards, and understand the dynamics at play, such as the number of individuals present and the environment of the scene. This foundational assessment is essential for making informed decisions about the resources needed and the immediate actions to take.

The other options, while potentially relevant in certain contexts, do not serve the primary goals of an initial response. For instance, contacting local businesses may be important for community relations or gathering information later, but it is not a priority during the immediate response. Charging the involved parties is a legal step that typically occurs after the scene has been secured and information has been gathered. Arranging for road closures can be necessary, but it generally falls under logistical planning after assessing the situation. Thus, while all these actions are part of law enforcement duties, the most crucial initial objective is the scene size-up, as it directly influences the safety and effectiveness of the response.
