Morality Question

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

You come across George W. Bush, 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.
