For the lawyers out there, this sounds like an excellent business opportunity. 20-minute legal emergency response to people in trouble at the security checkpoint. Could assist directly with regards to asserting rights, filing suits if the passengers' rights have been violated and extracting every dime that can legally be extracted from airlines that involuntarily re-book passengers.

Sorry that you had to go through this, and thank you for the very well-written account of how this ordeal looked first-hand.
