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?
