Coloradoans respond to automatic-weapon fueled mass murder by. . . going out to purchase more guns! Awesome.
Check out this map of the world that compares national gun ownership rates, their rates of murders by firearms, and the percentage of homocides by firearms (h/t civilian in the comments to the previous post.) The data are complicated–countries with high murder rates don’t necessarily have high rates of gun ownership, for example, but it’s clear that the U.S. stands out among its peers of developed nations with stable democracies.
