Moral Question

Here is a moral question for you. This is an imaginary situation, but it may
be interesting deciding what you would do.
The situation: You are in the Midwest, and there is a huge flood in progress.
Many homes have been lost, water supplies compromised, and infrastructure
destroyed. Let's say you're a photographer out getting still photos for a news
service, traveling alone, looking for particularly poignant scenes. If you were
to stumble across Bill Clinton struggling to keep from being swept away in a
raging river and you had a choice of rescuing him or getting a Pulitzer
prize-winning photograph of the death of a President, what shutter speed would
you use?
