Imagine this scenario, I'm wandering outside a storefront with my cell phone looking for a good signal, not really paying attention to what is going on around me. I'm stopped by a police officer that says something like, "Sir, please pay attention, you almost stepped in that open man hole," or, "Sir, you seem lost, can I give you directions?" Now, how should I respond to this? Normally, in polite society, I'd thank the officer for his/her concern and continue on. But with a law requiring I inform a police officer that I am armed did this interaction trigger the need to inform? What if I stopped and engaged the officer to ask for directions to a place with Wi-Fi that is nearby? Suppose while I was doing this a car rear-ended another nearby and the police officer asked if I was injured and/or if I had seen what had happened? That is an interaction with a police officer, but bringing up the fact that I am armed does not seem to be relevant to the conversation and would likely only confuse the officer on why I would mention it.
§ 2003-A. Duty to inform law enforcement
When an individual who is carrying a concealed handgun pursuant to the authority of this chapter first comes into contact with any law enforcement officer of this State or its political subdivisions or a federal law enforcement officer during the course of any arrest, detainment or routine traffic stop, that individual shall immediately inform that law enforcement officer of the fact that the individual is carrying a concealed handgun.
Note, during the course of arrest, detainment, or traffic stop.
In your scenario, you would not be required to inform because you are not detained. It's a consensual encounter.
