Disaster Photos

With all the wonderful things to photograph who would want to be a disaster photo-journalist?  It's a specific need that has to be filled.  The public needs to be informed of everything, not excluding disaster photographs.  I've touched on this subject before on our old site photography blog.  I think of Katrina and all the horrific images.  However, there were images that warmed the heart too.  As a photo journalist we have to think of everything news worthy.  It's those of us who dig deep and find stories that have the real talent.  The photography doesn't have to be Time-Life quality to create emotion but should be really close.  Are there any photo journalists out there?  Tell us what you think about doing disaster photos. Just the nature of the title with the word "disaster" it sounds a little frightening but isn't it someones civic duty to capture news and history as it happens?
