When responding to a crime scene, what factor takes priority over evidence preservation?

When responding to a crime scene, lifesaving takes priority over evidence preservation because the primary responsibility of law enforcement officers is to protect human life. If there are victims present who require medical attention, officers must first ensure that they receive the necessary care, which may involve calling for medical assistance or administering first aid.

While evidence preservation is critical to ensure the integrity of a crime scene and the investigation, it must not come at the expense of a person's health and safety. Officers are trained to assess the scene and determine if there are individuals who are injured or in imminent danger, and this assessment will guide their immediate response.

In considering the other tasks, such as evidence collection, witness interviewing, and report documentation, these activities can only take place once any potential lifesaving measures have been addressed. In the hierarchy of priorities during a crime scene response, protecting life is the foremost concern, setting the foundation for subsequent investigative efforts.
