This Federal law exempts qualified active and retired law enforcement officers from local and State prohibitions on the carrying of concealed firearms while off-duty across state lines
A qualified active or retired law enforcement officer who is carrying the proper identification may carry a concealed firearm across state lines. However, private citizens are allowed to prohibit the possession of a concealed firearm on their property. A State can restrict the possession of a concealed weapon on its property (i.e. park, school, building, etc.).
Qualified retired law enforcement officers must carry on their person, a photo id issued by the agency from which they retired from service as a law enforcement officer. That photo ID must indicate the person has been tested or otherwise found by the agency to meet the standards established by the agency for training and qualification for active law enforcement personnel to carry a firearm of the same type as the concealed firearm.
Alternately
Qualified retired law enforcement officers must carry a photo id issued by the agency from which they retired from service as a law enforcement officer and a certification issued by the State in which they reside that indicates they have been tested or otherwise found by the State to meet the standards established by the State for training and qualification for active law enforcement officers to carry a firearm, of the same type as the concealed firearm, within the past 12 months.
