Love the "dead-eyes" on those 3 officers. The only one who's eyes are shown clearly is the young driver. Here's my interpretation: the driver is new around here, inexperienced, looks pretty scared, however there is still humanity left in him. On the other hand, those 3, experienced fighters, have done their fair share of destruction and mayhem, seen even more of it happening right in front of their eyes. Their humanity is lost.
That's how I see it, or at least, that's what came to my mind when I saw this drawing.
