An active duty marine flew Los Angeles to Taipei and was connecting on China Airlines flight CI120 to Okinawa when he was found with 40 rounds of ammunition while going through transit security. The marine explained that he had ‘forgotten to take them out’ of his bag, but he wasn’t carrying a gun to use them with in any case.
The bullets were immediately visible to screeners in Taipei using a standard x-ray machine. To screeners at LAX, not so much. They’re too busy manipulating advanced imaging machines so they could fondle attractive passengers.
