Journalistic Boundaries?

While reporting from Haiti, Anderson Cooper and his crew ended up in the middle of a looting riot that turned violent. As a journalism student (which I was, briefly) you are taught that part of journalistic integrity is to remain uninvolved because if not you are then making the news rather than reporting it. Lines like that tend to blur in extreme situations when journalists are often early on the scene. Cooper bravely ran into the melee to help a young boy who had been struck in the head with a concrete brick. I think he made a courageous choice, and a humane choice, by getting involved. The video is graphic and if you're squeamish around blood do NOT watch. But to me, it is a true example of journalistic integrity.
