I probably shouldn't, but I will explain how I'm thinking:
1. Famous person with a habit of publicly characterizing all gun owners as evil people who have the intent to harm innocent bystanders. The fact that he killed a *truly* innocent bystander with a gun is tragic irony.
2. It's like watching a pile-up on the interstate. And the story keeps developing into more and more of a morass of stupidity. On many, many sides.
3. It shouldn't have happened. There were NO extenuating circumstances that even begin to explain how this happened. No other party threatening, no life or death situations, just ...nothing.
4. Someone made a thread about it. And it's not devolved into political mudslinging. Yet, at least.
As far as the other gun-related incidents you related, I don't know about most of them. Yes, I'm a wee bit of an ostrich, but I like my sanity and would like to maintain it, so I don't read much news until something piques my curiousity. Oh, and by the way, Kyle from Kenosha didn't kill an innocent bystander. He made a conscious choice to protect himself against men who were trying to attack him. I hope that if I am ever in a self defense situation and end up in court, you will forgive my breakdown, because I will be breaking down remembering the terror of that moment, and I'm not even a kid. And that one has been so highly politicized that I'm sure it would have been locked nearly immediately, anyway. I don't have a clue about any of the other situations, so I'm not going to put myself at risk of spreading false information by commenting on them.
My two cents. Worth what you paid for them.
