Bullets found onboard Carnival vessel

Two .22 caliber bullets were found in the Carnival Celebration's lobby by a passenger debarking Thursday morning. The passenger turned over the ammo to the information desk, who told the ship's security officer, who informed Customs and Border Protection, who involved the Coast Guard. Embarkation was then delayed by an hour while authorities searched the vessel from stem to stern--finding nothing else out of order.

The incident occurred in the ship's homeport of Jacksonville, Florida, and authorities verified that all metal detectors there were operating properly.

The question of metal-detector sensitivity is a recurring one wherever they're deployed, whether in airports or cruise ports. It's a subjective judgement. They can't be set to detect any metal at all, else the rivets in jeans would cause delays and screening would take forever. So does it surprise us that two bullets could slip through? Not really. Just so long as whatever gun they go with didn't come along with them.
