Totally outta left field, but DSS MSD wears a uniform that is similiar. That is if those are BDU bottoms and not jeans. (I can't really tell, Adam help me out here) But like Wolfpack said, could be anybody.
Defenetly something going on but not a racket at all, look at the people, they just walk by, theres some afghan security members at the left talking to each other, in the backgournd thereīs a tall guy witha hat he look blur i guees he is american. the so call devru with italian face i guess he is some sort of liazon any way he is the onlyone working. o also look at the guy in tan hes inteligence, he looks stiff and non athletic but he is the only who saw the picture coming and he turned away.
