Your "unedited words": "That stunt should never have happened where it did." It happened on a military firing range, in the presence of experts. Demanding more is requiring of them essentially perfect foresight. This is equivalent to requiring them to guarantee accidents are impossible. I do disagree that it "should never have happened where it did", because I reject the notion that causality can be reversed like that. They performed the experiment in a reasonable location for what they knew at the time.
