What term describes a subject that is compliant and agreeable with a security personnel?

The term that best describes a subject that is compliant and agreeable with security personnel is "cooperative." This term signifies an individual who is willing to work with others, in this case, security personnel. When someone is cooperative, they actively participate in the process, follow instructions, and assist in achieving a safe and orderly environment. This behavior is crucial in security contexts where collaboration can enhance effectiveness and reduce misunderstandings or conflicts.

"Compliant" could also describe someone who adheres to rules or directives, but it does not inherently convey an openness to collaboration or participation to the same extent as "cooperative." On the other hand, "resistant" denotes an unwillingness to comply or cooperate, and "nonchalant" indicates a lack of concern or indifference, which does not align with the notion of being agreeable or engaged with security personnel. Understanding these distinctions helps clarify why "cooperative" is the ideal choice for this scenario.
