We don’t know the motive yet. It seems to be targeted. At least he didn’t randomly kill dozens of people who didn’t have anything to do with it, whatever it is. They’ll catch the guy sooner or later if he’s still alive.
I understand, there might be the other reason why he did it. But it still doesn’t negate the fact that there is a real true problem with the health insurance industry also now that it has been brought to light. Can’t put that toothpaste back in the tube because his motives were actually different.
