LEOs carrying arms on commercial flights must adhere to which of the following regulations?

Law enforcement officers (LEOs) carrying arms on commercial flights must adhere to the regulation regarding the avoidance of irritants or incapacitating substances. This is important to ensure the safety and security of all passengers and crew during flight. The use of such substances could lead to uncontrollable situations, panic, or potential harm to travelers in a confined space. By prohibiting irritants and incapacitating substances, the regulation promotes a secure environment on commercial flights, which is critical given the challenges of enforcing law and order in an aircraft setting.

Carrying tear gas or any similar substance can introduce significant risks, especially in the confined and sensitive environment of an aircraft where an incident could have catastrophic consequences. Therefore, this regulation aligns with safety protocols designed to ensure that a law enforcement officer's presence serves to enhance security without compromising passenger safety.
