Here Asma al-Assad, Syria's First Lady is exhibiting a subtle "Jaw Jut". As with all first ladies, she is put in many a situation for which she does not particularly care - yet her "game face" is much better than most. Here her mandible is protruding a mild amount. This is a significant sign of anger and while she has no other visible signs of this emotion, we can be sure of its presence. In men in particular, this is a signal that their anger may escalate - so take heed. Like most negative nonverbals, be wary that those displaying it are rarely aware of the presence, the level or the progression of their anger. Asma is perhaps, if only for a moment, a relative and rare exception to this rule. Anyone can spot dramatic anger - but it should be your goal to spot its subtle signs.
