What should be done to all patients at the CCP by law enforcement?

The appropriate action for law enforcement to take at the Casualty Collection Point (CCP) is to search all patients for weapons. This step is crucial for ensuring the safety of both the patients and the responders at the scene. In an active shooter incident, there is a potential risk that individuals may be armed or may have concealed weapons, which could pose a danger in a chaotic environment. Conducting searches allows law enforcement to mitigate these risks and maintain control of the situation.

Searching patients helps protect other victims, medical personnel, and law enforcement officers, by preventing any further threats. Ensuring that no hidden weaponry is present is essential for establishing a safe area where medical treatment can occur without the added danger of an armed individual potentially re-entering the scene of the incident.

The other options, while important aspects of patient care and management, do not prioritize immediate safety in the context of an active shooter situation. Documenting medical histories, providing psychological evaluations, and checking for allergies, while necessary at some point in patient treatment, would not take precedence over searching for weapons in a high-risk environment.
