On a side note, I haven’t seen anything mentioned about the size of the perp. From the pictures that have been released of Sapirman, he appeared to be a pretty skinny guy, maybe less than 140 pounds and of average height.
Considering how thin he was, he made for a pretty small body mass target. With all the other data, together with what the size of the target would have been, these shots are beyond miraculous . . .
It is not a mmiracle that Dicken was extensively practiced. His grandfather taught him and practiced him a a lot all while he was growing up. I have seen mention that Dicken may be high functioning autistic and if so that would figure in his quick reactions and accuracy. I have two such children and because of that I know others. They have a capability of concentration that is awesome and if they get into a project they are intense and reach pretty close to perfection. The intense practice itself would have rendered Dicken's reactions fast and automatic. Perhaps his secret name is Kyle like Chris and Rittenhouse.
