Forget about being seen naked. The bigger issue is that it's all security theater and does little to actually make us safer, yet it costs us an extraordinary amount in cost and lost time.
Evidence? (or reasoning)
In the second millennium airport security was introduced and many fewer viking raids took place
In this millennium with greatly increased airport security there have been no viking raids on any part of the British isles.
See dalke's reply to me below for an actual response:
If you calculate the lost man hours of productivity on airport security, we're getting killed everyday.
There are definitely ways to avoid this, but it's probably best discussed outside this forum.
