Suspicious Facial Detection?

Canadian Air is planning to used trained experts to study people’s faces and determine if they are acting suspiciously and are therefore a security threat. The objective of the program is to screen for suspicious people and behavior, in addition to screening luggage in security checkpoints. 


Behavior detection officers will be looking for people whose behavior may indicate abnormal stress, fear or dishonesty. 


Programs similar to this have been run in several countries, including the U.S. and UK, and officials say that they have brought in 70,000 people for questioning and made over 700 arrests. However, none of those arrests have been terrorism-related.
