CHICAGO TRIBUNE: How gun-free zones invite mass shootings. Spoiler: It’s pretty much how you’d figure. But you may not know this:

Of the 97 countries where we identified mass public shootings, the U.S. ranks 64th per capita in its rate of attacks and 65th in fatalities. Major European countries, such as Norway, Finland, France, Switzerland and Russia, all have at least 25 percent higher per capita murder rates from mass public shootings.

While Americans are rightly concerned by the increased frequency and severity of mass public shootings, the rest of the world is experiencing much larger increases in per capita rates of attack. The frequency of foreign mass public shootings since 1998 has grown 291 percent faster than in the U.S.

I didn’t, and I pay attention.
