There are a half dozen or so attempts to explain, but Albaby is right, we just don't know why, and I've learned to live with that.
On guns, when I proposed getting rid of barrel magazines, some gun owners were receptive. But when I proposed limiting magazine capacity to 10 rounds - big resistance. I described several instances where either police or hostages made successful moves against a shooter. That wasn't persuasive. I came to the conclusion that we might get somewhere after the current generation of gun enthusiasts dies off.
