So long as you have a society with a lot of guns- and America has more guns per capita than any other county in the world- children will be at risk of being shot. The questions are how much risk, and what, if anything, is being done to minimize it? If one thinks of various ways in which commonplace items, from car seats to medicine bottle tops, have been childproofed, it’s clear that society’s general desire has been to eliminate as many potential dangers from children as possible, even when the number of those who might be harmed is relatively small. If one child’s death is preventable, then the proper question isn’t “Why should we do this” but rather “Why shouldn’t we?” It would be strange for that principle to apply to everything but guns.
