It's never funny when someone gets arrested. It's even worse when the person is an apparently law-abiding 57-year-old (a little long in the tooth to be a terrorist, wouldn't we agree?) traveling with his family.
I suppose it would be too easy to say, "Excuse me, sir. You apparently forgot that you have a gun with you. We're going to have to confiscate it. Have a nice vacation."
No, I'm not kidding.
