It’s a Klingon proverb. But more likely taken from the Islamic tradition of “A thousand...”
But more to the point is the INTENT of the shooter. His obvious INTENT was to slaughter. My daddy always told me to have absolute confidence in my shot, big game hunting. You know, that my INTENT was to kill. But that INTENT is dampened by RESPECT.
In this case, IMO, armed with some sort of multiple bullet weapon on a “closed” course with 700 + - targets, a professional killer with the INTENT could have amassed a far greater number of kills.
And do not misunderstand me. This is a monstrous act and a terrible tragedy. Just replying to your question.
Thank you for your response, answers many question.
As a former hunter (VN cured me of the hunting desire ... having been hunted myself), I no longer hunt ... although I enjoy the results of other hunter ... love venison.
