It's ten years since Sandy Hook. My daughter was the same age as those kids, attending a small-town elementary school in Vermont, a state with - at the time - gun laws about as free & easy as Texas. I learned a lot about guns over the next few years, especially the ways Americans fetishize them, and I suspect now we'll never have meaningful gun control.
After about a week of weird silence, the head of the NRA angrily insisted that the solution was more guns, in classrooms, everywhere, and blamed the godless left: all the lunacy to which we have become accustomed.
In retrospect, this looks like a turning point, leading directly to the moment we're in now, in which a heavily-armed, angry minority of the population insists on the primacy of their rights with utter indifference to the rights of everyone else. Challenge their ideas or even their funhouse-mirror version of the facts, and the threat of violence burbles up. In other words, Trump, Inc. was watching the news, too, in 2012.
