Could shooter have known which one was his little girl?
I believe the answer is "yes," definitely could have known. May even have written about it. But...perhaps no one wants to know one way or the other.
Every LEO I ever worked with has told me, "There's always a reason and it's usually not difficult to figure out." But only LE are supposed to know it, apparently. Most LEO's think the rest of us should also know it - but the public, apparently, is divided on what they wish to know.
Speculation may be better than knowledge, in terms of maintaining our comfort zones.
IMO. (I don't agree, but that's immaterial).
This is a good point. It seems like we can't win either way.
We could do better, if only we realized that not all points of view are equal and decided to try and create bridges between the most opposing viewpoints.
Judging from cross-cultural and historical studies, though, it is probably too late for the current generation.
We will only "win" when the truth is plainly out there. But, mystical positions that are not susceptible to proof are out there too, and people flock to those. I've done it myself, long ago. I don't know what the answer is, but I do know that it takes more than one lifetime to even begin to understand the situation we have on hand right now.
It's a war-like situation, and harming children is the most upsetting thing of all, to me. Sometimes I wish I hadn't decided to study primates.
