The biggest subjective concern I'd have is safety and being able to help. Those aside, I've only seen two or three burning cars in my life - too interesting to pass on aesthetic grounds.
Seeing that my photography is mostly snapshots/memories, I'd be capturing the moment - so it would be more of the newspaper analogy.
However, if I had a number of pictures I were displaying for whatever reason (publication, web, slide show, etc), then color (or whatever aesthetic concern I were illustrating) might influence the choice of what I show. The picture would not have been taken for the purpose it would later serve.
Of course, if I were asked about it, I may not admit how things really transpired
On the other hand, choosing photos that illustrate a subject is not the same as claiming to have taken it for that purpose. Most avid photographers have quite a portfolio of images to draw from.
