I have a moral question for you. This is an imaginary situation, but I
think
it is fun to decide what one would do.

The situation: You are in the Middle East, and there is a huge flood in
progress. Many homes have been lost, water supplies compromised and
structures destroyed.

Let's say that you're a photographer and getting photos for a news service,
traveling alone, looking for particularly poignant scenes.

You come across Osama Bin Laden who has been swept away by the floodwaters.

He is barely hanging on to a tree limb and is about to go under.

You can either put down your camera and save him, or take a Pulitzer Prize
winning photograph of him as he loses his grip on the limb.

So, here's the question and think carefully before you answer the question
