NYC and New Jersey Bombing Suspect Ahmad Khan Rahami is now in Custody. The grainy photo above is from a routine public ID imaged in the past (it's NOT his mugshot).
Note his jaw jut, the tension of his mid-face, the flaring of his right nostril, eyebrow lowering, the tension of his lower eyelids and his partial upper eyelid closure.
This facial expression indicates an amalgam of anger and contempt. We're all allowed to feel these emotions - for we are all human. However whenever anger, contempt and/or disgust are expressed chronically - it's a strong indication of impulse control disorder. While this phenomenon has always been true, but with the ubiquity of social media it's relatively easy to vet those who we may hire, be employed by, date, etc. Of course a very small percentage of those who frequently exhibit these nonverbal signals will go on to commit acts of terror or violence, but they will have difficulty controlling their temper.
