I believe they was referring to the following:
Q - How does the law apply to licensed individuals from other states who move to New York and wish to posses their handguns here?
New York State currently has no reciprocal agreements with any other states and does not recognize any other state's licenses. It would be unlawful for an individual to move to New York State and possess handguns in the state without first being licensed by the county in which the individual will reside.
There are two options for individuals already in possession of handguns in their home state.
* They must either leave the weapons in the possession of an individual in their home state who may lawfully possess them until such time as the owner can legally possess them in New York State, or
* They may leave them in the possession of a licensed gun dealer in their home state who would be willing to hold them until that individual can lawfully possess them in New York State.
In either case, the weapons can only be lawfully brought into New York State via a licensed dealer in the home state shipping them to a licensed dealer in New York State from whom the owner may take possession.
Weapons personally brought into New York by the owner would result in forfeiture of the weapon and possible criminal charges brought against the owner.
A few years ago, a UA CSR at LGA informed me that they often have issues when people declare firearms to them, because often those making the declaration don't have the proper license for NYS. However, I don't know how enforcement of this works with UA/TSA reporting such to the proper police authority. If it is illegal to have a weapon in NYS, then I assume TSAs reporting of weapons to PAPD would be the same as TSAs reporting of other non-prohibited TSA illegal substances or objects found during searches.
