I've jumped in on those threads from time to time quoting statistics, mostly to illustrate that many of these incidents are not that unusual. I usually wonder why a few each year are singled out of the much larger pack. I guess some have some unique aspects.

I usually quit reading them after a few posts. Not because they are depressing, but usually because there isn't much to say about them.

I don't like that they happen. Just as I don't like that thousands of people are killed by drunk drivers every year. That children are abused. That people are starving. That the judicial system is unfair. That lunatic men decide that their wives/girlfriends are not allowed to live without them. Etc.

I do wish the world were a kinder place.

As to the question about posting here, as usual I'm not going to purpose a rule be established. Sometimes people need to post things and there is usually someone else who connects to the thread. But they don't do anything for me - although if the victim were a BF 50+'er, then I would have an interest in knowing about it.
