In this recently published GoPro video of a man who is the victim of an attempted robbery, provides a very real example of some of the nonverbal warning signs often seen just prior to (and here during) an assault/attempted assault. Alex Hennessy, who is traveling the World making a film series named "Global Degree" very luckily escaped with his life and no possessions lost while bicycling through La Boca - a neighborhood (aka barrio) within Buenos Aires, Argentina.
What follows is a partial body language analysis of the Canadian Videographer's attacker (later apprehended by law enforcement).
In this image (captured during the 0:29 segment) we see the gun-wielding man with his jaw jutting outwards (forwards) and with only his bottom teeth showing.
This Jaw Jut and baring of the bottom teeth is an extremely reliable indicator of a heightened adrenaline state associated with the rage of an attack.
Don't stop there though - look at his eyes and the tissue around them. His right eye is opened widely - indicating elevated adrenaline. His eyebrows are pulled together and the central (medial) portions are directed downwards. His nostrils are also considerably flared.
Taken as a whole, or even just portions of this nonverbal cluster, it's extremely indicative of a person who is in an uncontrollable rage. Whenever you see this body language, immediately retreat and/or take cover. If these two options aren't possible defend yourself and attack preemptively. Recognizing dangerous nonverbal signals is profoundly necessary and is lifesaving component of any threat assessment training/preparation. Ignore them at your peril.
