I wonder if there is a real list of stuff security wont let ya bring through the airport, or if security is just a bunch of guys seizing anything they see with maybe an LED and a few wires and buttons hanging off it. Guess if they dont stop enough people be it for genuine or non-genuine reasons, their boss wont be able to boast about how many 'dangerious items' their 'highly-trained security team' stopped from making it onto US airlines :P Gotta make the big man look big!
