Whoa

I just checked the newspapers in Columbia, Missouri. I try to keep up with the news since I worked for the Columbia Missourian. It seems there has been a crime wave.

Slain scientist
Cop shootings
Convenience store stabbing
Violent robbery
News photographer arrested

The last link is especially interesting to me. When you take pictures of a crime scene or other content-sensitive things, its hard to know the limit. On one hand, photographers have the right to document community happenings and make them available to the public. However, there is a point when you have to back off and let the police do their job without interfering. The question is, when are you standing on the line and when are you stepping over.
If you look at this link and then click back to the main page for the Columbia Tribune, you will notice the paper still published a photograph taken by the photographer who was arrested. Is it right to publish a picture that was taken illegally?
