Which of the following is NOT a requirement for licensed armed private investigators carrying concealed firearms while on duty?

Maintaining a visible identification badge while on duty is not a requirement specifically related to the carrying of concealed firearms for licensed armed private investigators. The primary focus of the regulations regarding armed private investigators revolves around their ability to carry a firearm safely and legally, which encompasses aspects such as keeping the firearm concealed, holding a valid investigator license with the appropriate firearms endorsement, and having a valid driver's license, if required by law.

The requirement to keep the firearm concealed is intended for ensuring public safety and complying with regulations regarding firearm visibility. Additionally, possessing a valid investigator license with a firearms endorsement establishes that the individual has met necessary training and legal standards for responsible firearm use. While having a driver's license can be relevant for identification or operational purposes, it is not directly tied to the specific requirements of carrying a concealed firearm.

Visibility of an identification badge might support overall professional conduct and public trust but does not specifically pertain to the regulations governing concealed firearms for private investigators. This distinction underscores the importance of understanding what is specifically regulated in relation to firearm handling and public safety protocols in the context of private investigation work.
