The reporters are covering local and regional stories.  Stories which are not covered by wire service releases.  The local crime reporting is, indeed, usually based, I think, on the reports filed by officers involved.  I do agree that there are times that information is pretty "basic" and more detailed info. would be interesting.  Again, this varies from reporter to reporter.  For example, I think Saul Hubbard does a great job covering Lane County government and providing background details and that "in depth" coverage you seek.  regards, Gary
