What police chief in his right mind would order a raid on a newspaper office?

Imagine a world where a local newspaper makes the local police chief mad because the editor discovers a long-forgotten drunk driving conviction during a divorce case of a local business owner. The newspaper never publishes the story because of trouble verifying information but the police chief gets a local judge to issue a search warrant allowing the seizure of newspaper records, including the computer on which the identity of the newspaper’s confidential source on the DWI conviction is stored.
