They use regular sized pieces of paper as targets? They don't even use a life-sized picture of a head and put it at a sniping distance? Based on this, I can believe that they were simply re-purposing mugshots that were printed to show to someone reporting a crime.
"Yes, it was a black man who held up my store."
"Does he look like one of these men?"
At that point, do you really think the police are going to show someone a set of mugshots with 1 black guy, 1 Hispanic guy, 1 Asian, and 3 white guys, to show cultural diversity?
Again, that's assuming these were re-purposed mugshots that were printed for another purpose. It doesn't make sense to print targets this size for sniper practice. Shooting a smaller picture of a head at a closer range is not the same as shooting a real sized picture at a longer range, though the target may take up the same size in degrees.
