The key to stopping this insanity was mentioned in a post on Page 1. (Sorry - have been away from an internet link for several days so I'm playing catchup)
Make sure that you and your crew have turned up on time and in all respects ready to fly. When the 'security' neanderthal stops you for some petty infringement like a ID/Sec Pass issued for some other BAA airport then simply call your operations centre, tell them the story and take the boys and girls back to the hotel (or nearest Starbucks) to wait whilst your employer sorts it out.
Nothing like having a gate blocked by a crewless aircraft to catch the airport operators attention.
You all know how the system works - use it against them!
