In the wake of the shooting, the immediate aftermath, a lot of people suddenly got the health care they'd been denied. It's true that they didn't change long term, but for a little while, they did.
It is so horrible to know that these people need to be actually afraid or they'll continue to hurt people.
Yeah, last I checked, the US has elected school boards that decide what books to allow in libraries. Our school boards used to have tax levying power, so electing them was important, but now? I'm not sure they do much now other than draw salaries and give parents a place to complain, and a proper ombudsman could do that.
