So a middle eastern man, "soldier", falls neatly on the stairs, conveniently with his butt on a step so he is perfectly placed where his body can remain rigid but comfortable. His head is not even on a step, and his fingers are curled. The attending person, dressed in a suit, steps between the fallen mans arm and body with his left leg, leaving his next step to be ON the man, or over him on the other side. Not my first instinct, but OK. I wonder where his right foot landed a few seconds later? Was he doing this in anticipation of having to straddle him? Even if he was, any medical trained personnel would not approach someone like this, nor do CPR in a position straddling the patient. Plus he looks like he's pressing on his chest, or leaning on it. Why isn't anyone else in suits reacting? Why is the other visible suit just standing there? Human reaction is to at least go down to help.
