At Front Lines, Bearing Witness in Real Time -

"Bearing witness is the oldest and perhaps most valuable tool in the journalist’s arsenal, but it becomes something different delivered in the crucible of real time, without pause for reflection. It is unedited, distributed rapidly and globally, and immediately responded to by the people formerly known as the audience.
It has made for a more visceral, more emotional approach to reporting. War correspondents arriving in a hot zone now provide an on-the-spot moral and physical inventory that seems different from times past. That emotional content, so noticeable when Anderson Cooper was reporting from the Gulf Coast during Hurricane Katrina in 2005, has now become routine, part of the real-time picture all over the web.
The effect, as Ms. Sontag pointed out in an essay in The New Yorker in 2002, is anything but certain.
“Making suffering loom larger, by globalizing it, may spur people to feel they ought to ‘care’ more,” she wrote. “It also invites them to feel that the sufferings and misfortunes are too vast, too irrevocable, too epic to be much changed by any local, political intervention.”
So now that war comes to us in real time, do we feel helpless or empowered? Do we care more, or will the ubiquity of images and information desensitize us to the point where human suffering loses meaning when it is part of a scroll that includes a video of your niece twerking? Oh, we say as our index finger navigates to the next item, another one of those. "
