That's pretty much what I saw or perceived in that picture: clueless, disconnected self-absorption much akin to the more common occurrence of rubberneckers who snarl up traffic on the freeway whenever there's an accident.
But they were a safe distance from the scene and did not appear to be obstructing anything. If you assume that they do not have any first-responder training it is not a bad thing that they were not adding congestion to the roads by trying to cross the bridge to get a closer look or to make a video of it for YouTube.
