Is it the responsibility of the CSA to notify each LEO of other armed individuals on the aircraft prior to boarding?

It is indeed the responsibility of the Customer Service Agent (CSA) to notify law enforcement officers (LEOs) of other armed individuals on the aircraft prior to boarding. This is crucial for maintaining situational awareness and ensuring the safety of passengers, crew, and law enforcement personnel alike. The presence of armed individuals can impact security protocols and the overall response plan should any incidents arise. By informing LEOs, the CSA contributes to a coordinated and effective security strategy, allowing law enforcement to be prepared and implement necessary measures during boarding and flight operations. This proactive communication helps to mitigate risks and promotes a secure environment onboard.

In the context of this question, other responses hint at varying degrees of awareness or readiness to inform LEOs, but the clarity and emphasis on the CSA's obligation underscore the importance of communication in ensuring safety and security during flights.
