Oh yes...
Political cost of being seen to do nothing: high
Political cost of being seen to do something which sounds impressive but is actually ineffectual and eventually fails: much lower, maybe nil if it takes long enough to fail
Cost of buying / running acutal scanning measures: nil - pass to passengers
Benefit of buying / running scanning: high - big profits for security theatre companies
[guess which of the above groups lobbies the politicians ?]
Cost of increased security queues: nil (well, for the airport...)
Benefit of increase security queues: lots - charge em more for a fast-track queue!
Cost of increased check-in to gate time: nil (except for the pax...)
Benefit of increased check-in to gate time: lots more time in the shopping mall...
...and so on.
