In the wake of this morning's tragedy in London, someone on Flickr
already set up a photo pool
. So far, it appears that the photos are generally just screen grabs of the TV news, perhaps those who were there, and those who operate security cameras in the stations could post their photos from before the attacks, and try to identify the perpetrators. A warning - the pictures don't appear graphic as yet, but as the day progresses, I expect that they will get to be so.
