This photo is a two shot, where both of the people in the photograph are doing the same action although with slightly different emotions. The fact that they are both wearing the same smart suit, suggests that they are co-workers in business, but they are also both holding a gun, looking quite comfortable, which when you link the two would make you either think that they are some sort of partners in assasination, or partners in the police force.
They are both lit up by the light coming from the window, which you cannot actually see anything out of, which suggests it is some sort of heavanly light. This is contrasted by the expressions on their faces, which look, although comfortable like they have nothing to worry about they do look quite mad at whatever they are pointing there guns at.
I think that the fact that one is black with an afro, and the other is white with long hair, is showing how different they actually are, even though they are in the same profession and wearing the same clothes.
In the photo, the light is shining off of the gun, going down the barrel, which suggests that they could be religous, and believe what they are doing is right.;
