When we cannot hear what is being said to us or about us, but we can observe facial expressions and hand gestures a different set of parameters is put into motion. Our frame of mind on any particular day will have a large effect on how we interpret what we see. Laughter for instance can be taken as either positive or negative are they laughing at you or with you? Various had motions can be taken in a myriad of ways.
If you look at it from another perspective this is another example of what could lead to miscommunication. Before we make any rash decisions on what is meant by a person or group of people we should ascertain from the individuals exactly what is meant by their actions if the situation it is something that is important to us, if not then go on as normal. Often people are judged by supposition instead of fact, which can make what was a harmless comment or gesture into a major conflict.
The man in the red toque may be saying something negative or positive, he was probably the first person on the scene. He may be expressing an opinion of something completely different than what he is or was looking at. None the less from the perspective that we see him from he appears to be addressing the people behind him. If that hand in the foreground is his hand. A man in the center of the painting seems to be whispering something to the man in front of him, if that is in fact his hand. My point is conjecture comes from our imagination and that comes from god knows where.
Black and blue were used in the bodies and hands of the individuals as miscommunication can lead to very painful psychological bruising in the hearts and souls of human beings.
