There was a tragic incident of climate change Wednesday, or so Barack Obama might say. As I was driving home that evening listening to the still-sparse details on the San Bernardino shooting, the news report informed that there were two dead suspects, a man and woman. So I already knew more than the authorities were telling: I figured the two assailants were non-white, almost certainly Muslim. After all, if the police knew their sexes, they knew what they looked like. And if they’d been white, it would have been announced right away.
