The outrage after Parkland set off a moral reckoning and awakening—there’s a simple explanation for school shootings.
Americans of high-school age are 82 times more likely to die from a gun homicide than 15- to 19-year-olds in the rest of the developed world.

American gun culture in the 2010s is as blithely irresponsible as American alcohol culture in the 1960s.
