That's why you need to check the laws before going near a place. Just because we haven't seen a newspaper article about someone getting in trouble doesn't mean it's safe.

Here are a few examples:

Washington, D.C.: "A valid registration certificate is required for possession or transfer of any firearm." "Illegal to possess or acquire magazines of more than 10 round capacity." Thus, an airport in D.C. is one of the last places I'd want to be diverted to while legally transporting a firearm from safe place A to safe place B.

U.S. Virgin Islands: "A permit is required to possess, transport, or carry a firearm". There aren't too many safe destinations that you could be headed to where you might get diverted to the Virgin Islands though.

Illinois: "State-issued FOID required to possess any firearm."

Hawaii: "All firearms must be registered with local law enforcement within five days of purchase or 72 hours of import into the state, whether or not they are serviceable or not." So I was wrong about Hawaii, it's OK to be diverted there as long as your diversion is shorter than 72 hours. Hawaii is not a place you'd likely be diverted to anyway, it's kind of all by itself out there.

New York, New Jersey: You said you were already familiar with their prosecutions, so I won't quote any laws for them. But they're very bad.

Basically, any place that requires a license to own firearms, registration of firearms, or an FOID ("Firearms Owner Identification Card") is a potential Hell Hole you wouldn't want to accidentally end up in.
