Police and the media have had a close relationship but it has become an increasingly uneasy one. For more than a century, the mainstream United States media—mainly newspapers, radio, television and magazines—have depended on the police for raw material for a steady diet of crime stories. For its part, law enforcement regards the media as something of an adversary. The relationship has changed because of the growth of investigative reporting and of the Internet. Both developments have increased the volume of material critical of the police. At the same time, law enforcement has used social media as a means to bypass the mainstream media to try getting its message directly to the public. However, the news media in all of its forms remains a powerful interpreter of how law enforcement does its job.
