What is the purpose of notifying other armed LEO aboard an aircraft?

Notifying other armed law enforcement officers (LEOs) aboard an aircraft about their armed counterparts' locations is crucial for several reasons related to safety and security. In an environment where multiple armed personnel are present, clear communication regarding each officer's whereabouts helps prevent confusion and potential misunderstandings that could arise in a high-stress situation. This awareness is vital in maintaining control and ensuring a coordinated response should an incident occur.

Furthermore, knowing the locations of all armed officers can enhance situational awareness, allowing for more effective teamwork and support in operations that require law enforcement presence. This is particularly important in aircraft, which may be confined spaces where the movement of individuals must be carefully managed to avoid unintended confrontations or escalations.

While informing LEOs about emergency procedures, advising them on the flight plan, or ensuring proper baggage handling are important in their respective contexts, the primary rationale for notifying them about each other's locations is about tactical awareness and operational integrity in a potentially volatile environment.
