Facial security

Facial Security:

I'm of two minds about this story:

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.

On the one hand, body language is a very good way to get a read on someone's real intentions. It takes a lot of effort and training to overcome the natural, normal language (although actors can do it; it's not something that requires brain power, just practice).

On the other hand, it seems like the stress of airports could lead to a lot of false positives. Like if you were a father traveling with a four-year-old boy who kept dancing through the lines and pulling at people's luggage. I would expect a whole squad of police to be dispatched if someone got a look at your face while you were eyeing the miscreant.
