After decades of such tomfoolery on behalf of NYC, you'd think people would think twice before bringing their gun to New York City.
Me thinks some of these folks consider themselves above the law. For at least 15 years the NRA has been warning folks not to bring guns in luggage to JFK, La Guardia and Newark airports.
If your flight gets re-routed into one of these airports do not claim your luggage if it contains a gun. This happened to a friend of mine recently. He informed the airline he would not be claiming his luggage at JFK. His luggage was waiting for him at his destination.
