I think the photo below is a powerful image. It's of a supporter of Iranian presidental candidate Hossein Moussavi protecting a riot squad policeman after he was injured in skirmishes with protesters in Tehran. The green shirt is protecting the guy from his own fellow protesters, in other words, from the same people the police officer was probably beating just moments earlier. The green shirt obviously thought this officer had suffered enough and did not want him to be killed. A moving display of humanity. The image will stay with me for a while. I found the photo at Boston.com's Big Picture, which is a great site, btw.
Addendum: I just found this YouTube vid of the same thing happening. Moussavi supporters protecting a member of the riot police. The running commentary is in Italian.
Others taunt me with having knelt at well-curbs Always wrong to the light, so never seeing Deeper down in the well than where the water Gives me back in a shining surface picture My myself in the summer heaven, godlike Looking out of a wreath of fern and cloud puffs. Once, when trying with chin against a well-curb, I discerned, as I thought, beyond the picture, Through the picture, a something white, uncertain, Something more of the depths—and then I lost it. Water came to rebuke the too clear water. One drop fell from a fern, and lo, a ripple Shook whatever it was lay there at bottom, Blurred it, blotted it out. What was that whiteness? Truth? A pebble of quartz? For once, then, something.
