When I was walking through town with my camera gear today, some police were moving on a drunken hobo. He was hanging onto one of the policemans legs before being dragged off along the street by two officers, each dragging him by one arm as he wouldn't walk. Part pf me went 'wow that would make a great photo'. But most of me was too aware of a bench full of his mates and not wanting to enjoy someone elses misfortune so I kept walking. Usually I don't take people shots, but I know it was a one off photo opputinity and would have made a powerful raw image. I guess this is why I usually photograph landscapes and critters. Anyone else kick themselves for missing an opputunity?
