He pivots around, probably to detect where the biggest groups of students are, before he decides to stand still facing in my direction. We are separated by less than 10 feet and his arm is facing so precisely in my direction that if I ran straight ahead I would run right into the barrel of his gun. My body is incapable of moving, which gives him the easiest opportunity in the world for a point-blank shot. I am looking at him with eyes that are begging for mercy, but the eyes facing mine are as dead as the many bodies lying around him.  This is it, I am thinking. He is going to kill me.
