you can't use cameras because they think the footage could be reviewed to find ways in or spot security weaknesses. they're just protecting you and me. airports are pretty serious now. walk in, get searched, hop the plane, keep your knickers on during the whole experience and you won't get delayed, detained or strip searched.
or probed
i was watchin my aunt leave, and she had to take off her jacket and sandles, she had to walk thru the door thingy barefoot. reminded me of Punk'd where they tricked some celebrities with the same machine
