I think people are still trying to figure out what the story actually is. It does seem to have elements of Islamic terrorism to it, which is different from the other mass shootings we've had over the last couple weeks. But it also has elements of workplace violence / disgruntled employee. I hate that this gives some justification to the xenophobia that's been so prominently on display, but I can't deny that it does seem to follow almost exactly what people have been trying to make us afraid of, so maybe they have a point.
