The BBC links to video taken by passengers and passersby just after the London bombings last week. There’s some distant footage of the wounded and, perhaps, the dying, but thankfully nothing so clear or sensational that it would be appealing to voyeurs.

Surprisingly, some of the most compelling video is not of carnage at all. Much of the footage depicts people calmly evacuating Tube trains. One clip has audio from the train driver urging calm. I am deeply moved by the shots of people who are simply walking to safety. There’s no panic, just resolution. I’m sure there’s fear and confusion and all the swirl of dread one can imagine. It may be that other footage shows more of this response. The clips I’m seeing, though, offer a humbling portrait of human courage.
