Upon discovering a weapon used in a robbery scene, what is the appropriate action?

The appropriate action upon discovering a weapon at a robbery scene involves prioritizing safety and preserving evidence. Marking the location of the weapon and calling trained personnel to remove it allows law enforcement specialists to handle potentially dangerous items correctly. This approach minimizes the risk of unintentional discharge or disruption of potential evidence that could be pivotal in an investigation.

By leaving the weapon untouched, it ensures that the integrity of the crime scene is maintained, allowing for a thorough examination of the evidence. Trained personnel have the expertise to safely handle and secure the weapon without compromising its evidentiary value.
