What is the first priority of an officer when arriving at a crime scene?

Ensuring safety for themselves and others is the first priority of an officer when arriving at a crime scene. This crucial step involves assessing the scene for any potential threats that could endanger the officer or civilians, such as ongoing criminal activity, hazardous conditions, or individuals who may pose a risk. By prioritizing safety, the officer establishes a secure environment where they can effectively carry out subsequent duties, such as gathering evidence, interviewing witnesses, and conducting an investigation.

The other actions, while important, come after establishing safety. Immediate investigation without securing the scene could jeopardize both the officer's well-being and the integrity of the evidence. Looking for witnesses and searching for physical evidence are also critical but are secondary to ensuring that the area is safe for both the responding officers and the public. Prioritizing safety sets the foundation for all further actions during the officer's response to the crime scene.
