Why do you think it’s so important to get in this guy’s head, and to give him this graceful excuse of “maybe he just panicked?”

Obviously someone panicked. We can clearly see they did not line them up and actually shoot them with a firing squad.

But what is the point of this thought exercise? Where does it lead? To more “training” for the agents?

The whole thing is illegitimate and immoral. There is no need to engage with what was going on in the guy’s head. We are way, way too far past that point.
