Anthony Lane for The New Yorker's Daily Comment ponders on the woman with the shopping cart in the video in "Blood on the Streets of Woolwich":

4. Last, and strangest, is the woman with the shopping cart. As the speaker delivers his peroration, a middle-aged woman approaches from behind, pulling her cart, passing him, and carrying on by. She either does not notice what is happening, or prefers not to, or pretends not to, and who can blame her? We cling to the dictum voiced by W. H. Auden, that suffering “takes place / While someone else is eating or opening a window or just walking dully along.” But modern outbursts of violence, compounded with the modern means of capturing and publicizing them, may compel us to revise, or intensify, that observation. What Auden was pointing to, in his poem about Bruegel’s “Fall of Icarus,” were the lives that unfold, mild and oblivious, away from the scene of death or destruction: the ship that sails on, say, in Bruegel’s painting, while the boy with melted wings drops out of the sky. But what if life itself becomes an intrinsic part of the scene; what if someone else walks dully along, a foot or two away, just as death is lying there, and as the bringer of death is still crying his wares, and explaining what he sought to achieve? That is utterly disorientating, in its clamping together of barbarism and urban normality, of cloudy British weather and startlingly bright blood; and it may begin to account for the effect—bewilderment, shaken together with disgust and disbelief—that this footage is liable to have on those who see it. As we learn more, in the ensuing hours and days, of what occurred just before the cameras were switched on, that effect is unlikely to subside.

British Mother Confronted Hostile Hacking Suspects

By Nick Schifrin, ABC News, London, May 23, 2013

Anyone looking for a sign of British bravery in the face of terror should look no further than Ingrid Loyau-Kennett.

A British soldier had been hacked to death on the streets of southeast London Wednesday afternoon. His alleged killers carried butcher knives dripping with blood, stalking the scene, police nowhere in sight.

Loyau-Kennett's bus had just stopped in front of the killing. Some people might have shielded their eyes and fled. Instead, the mother of two and Cub Scout leader got off the bus and walked straight for the man whose hands were stained a deep red. He carried weapons. She carried only resolve.

"I just talked to him. He looked like a normal guy. He wasn't high, he wasn't on drugs. A normal guy pissed off with the fact, [as he said], 'Muslim women and children are dying in their countries by the hand of white men,'" she told Daybreak, a morning news program on the British channel ITV. "He was very, very close to me. He was almost touching me... I asked him, what's the point. [He said] 'war in London.'" [.....]
