"Was it just the way he looked, or did he, in the chaos, maybe call for God with a name that someone found strange?" Davidson wonders. One thing is certain: The media were quick to refer to him as a suspect and start tossing around theories about his involvement. It wasn't until yesterday afternoon that reports started referring to him as a witness who was, as one official put it, "at the wrong place at the wrong time." In the aftermath of the bombing, President Obama referred to Americans as selfless, compassionate, unafraid. "And yet, when there was so much to fear that we were so brave about, there was panic about a wounded man barely out of his teens who needed help," Davidson writes. The perpetrator could be anyone—an American, even—but even if it turns out to be a Saudi, "It still won’t mean that this Saudi man can be treated the way he was. ... It is at these moments that we need to be most careful, not least."
