from mcclatchy: Next time you go to the airport, there may be more eyes on you than you notice.
Specially trained security personnel are watching body language and facial cues of passengers for signs of bad intentions. The watcher could be the attendant who hands you the tray for your laptop or the one standing behind the ticket-checker. Or the one next to the curbside baggage attendant.
They're called Behavior Detection Officers, and they're part of several recent security upgrades, Transportation Security Administrator Kip Hawley told an aviation industry group in Washington last month. He described them as "a wonderful tool to be able to identify and do risk management prior to somebody coming into the airport or approaching the crowded checkpoint."
