I think this says you do have a duty to inform LEO's -
Sec. 4. 25 MRSA §2003-A is enacted to read:§2003-A. Duty to inform law enforcementWhen an individual who is carrying a concealed handgun pursuant to the authority ofthis chapter and who does not have a valid permit to carry a concealed handgun that hasbeen issued as provided in this chapter first comes into contact with any law enforcementofficer of this State or its political subdivisions or a federal law enforcement officerduring the course of any arrest, detainment or routine traffic stop, that individual shallimmediately inform that law enforcement officer of the fact that the individual is carryinga concealed handgun.
Sec. 5. 25 MRSA §2004, sub-§5 is enacted to read:5. Failure to inform law enforcement. A person who fails to comply with section2003-A commits a civil violation for which a fine of not more than $100 may beadjudged.
Unless I read that wrong....
