BAA is too busy doing other wasteful things, so no need to start with another stupid dog and pony "security" show.
Instead of wasting time trying to detect fake ID, BAA would be better secure the airplanes by spending some quality time trying to stop the failures to detect real WEI.
I couldn't care less about fake boarding passes. They work to get airside in the manner that refundable tickets' boarding passes work to get airside.
