If you're traveling with numerous weapons, should you just assume you'll be questioned? The AP reports that an American-Egyptian man who arrived in Cairo from New York was detained "as he tried to pass through customs with a metal box containing two 9 mm handguns, 250 bullets, several swords, daggers and knives. They say customs officials had been alerted after the weapons were discovered when the box was examined upon arrival Wednesday on an Egypt Air flight from New York's JFK International Airport in Cairo."

Update: AFP identifies the passenger as Mohamed Ibrahim Marei, "a US university professor of Egyptian origin," and gives a few more details: "Customs officials noticed the passenger looked nervous and decided to open his luggage. They found two handguns and 250 bullets hidden in metal boxes, the official said on condition of anonymity. In a secret compartment in the bag, authorities also found two swords, five daggers and six knives, he added." It's still unclear whether the luggage was checked in, but that sounds like a lot to carry on. Also: secret compartment!
