I felt a new wave of irritation, squelched it as I kicked into scientist mode. First rule: block mind-set. Don’t suspect, don’t fear, don’t hope for any outcome. Observe, weigh, measure, and record.Second rule: block emotion. Leave sorrow, pity, and outrage for later. Anger or grief can lead to error and misjudgment. Mistakes do your victim no good.
