We are never really going to know what happened here, because the principals are dead.
He was the right age for schizophrenia onset and there is a huge paranoid side that plays into that. She may have been unwittingly playing into his paranoid fantasies with her own fears and prepper stuff. We will NEVER know.
None of this explains why he'd kill the kids. Again, I don't believe we will ever know and if "talking heads" opine on TV, I think it will just be their best guesses.
We can talk all day about mental illnesses, too. It's an inexact science and we'll never catch everyone. There aren't cures, There are only controls. Sometimes. What sets off one person is inocuous to the next.
I think it's fear. I think gun owners and would be gun owners are worried about something like this happening to them or their families so they will cling to their guns or rush out and buy more.
What did Charles Barkley say? "I think, especially in the black culture, I don't know if it's a gun culture, it’s a crime culture. We, as black people, and I always say we, we don’t have respect for each other. You know? We got more black men in prison than we do in college, and crime in our neighborhoods is running rampant," NBA great Charles Barkley said. "I know everybody reacts when something like the Belcher thing happens, but being black, this is something you deal with all the time and it’s just sad. I’m a guy, I carry a gun. I carry a gun."
"I just feel safer with it, and I understand his point," Barkley said to McEnroe. "But for me, it's a personal choice. And like I said, it would take extreme -- obviously, I'm 50 years old and I've had it since I was 21, 22."
I think Barkley's statement reflects fear too.
