Chris Harper Mercer
Here Mercer is displaying Disgust with a component of Contempt.
Yet another mass shooting occurred earlier today near Roseburg, Oregon. The shooter, allegedly Chris Harper Mercer killed nine people and wounded seven at Umpqua Community College. He also died in a shoot-out with law enforcement.
From a nonverbal communication point-of-view, those who will go on to commit violent crimes - particularly mass shootings, bombing and terrorist-like acts - will extremely often display expressions of chronic contempt, chronic anger and chronic disgust.
It's very important to stress the chronic nature of these expressions. For as human beings we all experience anger, disgust and contempt - yet those who perpetrate such violent crimes will virtually always display these expressions CHRONICALLY.
Moreover the use of social media allows people to put forth a photo which characterizes the emotion which they wish to project out to the World. Thus a Facebook profile pic is essentially a form of a Rorschach test in reverse. Those who project chronic negative emotions are therefore telegraphing their intentions.
It's important to point out that, of course not nearly all people who chronically display anger, contempt or disgust will commit mass crimes. Yet such chronicity of expression is a signal of a personality disorder, impulse control disorder, or other mental disorder.

Here Mercer's expression is more subtle - he's displaying more Contempt with a lesser proportion of Disgust (yet they both are still present).
