smartness

[Drakhon]

I thought of lining them all up in a row, so that everyone in the back shoots the people in the front, and hoping that the guy in front doesn't hit.

I thought of that too, but I doubt 100 people can fit into a line 20ft or less long (they can't be more the 20ft from the prisoner), so I went with multiple rows that effectively make concentric rings.

I imagined that he would make a ring very close to him such that the first row's rifle barrels would be too long to point at him, and would thus point past him, and the others would all have to shoot their fellows in the back.

That's a better way to avoid that first row's shots; I hadn't thought of that.
