Stephen Paddock shot more than 500 people from the windows of his Las Vegas hotel room Sunday night, killing 58 of them. In the days since, a familiar story has been passed around the internet about the blinkered way in which we talk about these sorts of massacres. We’re so quick to blame Islamic terrorists, this story goes, that we don’t address the stark, distressing truth about mass shootings. The killers aren’t angry immigrants, by and large. They’re white men.
