NEW YORK (NYTIMES) - The name Zoe Roth might not ring any bells. But chances are you have seen her photo.

One Saturday morning in 2005, when Ms Roth was four years old, her family went to look at a house on fire in their neighborhood in Mebane, North Carolina. Firefighters had intentionally set the blaze as a controlled fire, so it was a relaxed affair: Neighbours gathered and firefighters allowed children to take turns holding the hose.
