Ha, no--but with that kind of body language, it definitely goes with the
ensemble! (A more-than-trivial question, though, might be what kind of Heckler & Koch-y goodness Blackwater is carrying in his messenger bag.
)
Kidding aside, this capture fairly vibrates with drama--that diagonal line you mention isn't just spatial, it's also a continuum of psychological states, ranging from the quiet confidence of the man on the cell phone, the slightly bemused but watchful mien of the guy rocking the John Bolton 'stache, to the slightly more agitated and aggressive stance of the third (because caught flat-footed?). The good publicans in the far corner are comic relief. Take it as a compliment that my mind automatically assigns a narrative arc ("ex-South African businessman's security detail on the streets of Philadelphia") to the proceedings--most of the movies I've seen lately haven't engaged me as much as this one "frame."
