In last year’s shooting near Oslo, 69 people were killed and an additional 110 injured. Germany, a country with some of the strictest gun control in the world — it requires not only extensive psychological screening but also a year’s wait to get a gun — has been the site of three of the worst five multiple-victim K-12 public school shootings in the world, all in the past decade. There are more examples of attacks in countries with strict gun control, like in Austria, Britain, France, Finland and Italy.
