In modern times, nearly every nation has had a psychopath or two commit a mass murder, regardless of how strict their gun laws are – the crazed white supremacist in Norway one year ago Sunday, the schoolyard butcher in Dunblane, Scotland, the École Polytechnique killer in Montreal, the mass murderer in Erfurt, Germany … the list seems endless.

And now the Aurora shooter last Friday. There have always been insane people, and there always will be.
