A healthy press tells the truth and raises hell. A healthy press asks pushy questions. A healthy press is suspicious, irreverent, intelligent, relentless, and puts the public right to know above everything else. A healthy press can be a real pain in the butt. A healthy press can sometimes step over the line into sensationalism and irrelevance.
Abuses are common, but the excesses of a free press are generally preferable to a controlled press.
Sometimes you strive to attain objectivity, and end up offending all sides. This can be a healthy sign. But it is exactly those stories that the public most needs to hear. Public needs to hear stories about how the system isn't working, in order to fix the system and keep it working. Otherwise problems persist, people lose faith in the system, rebel, military takes over.
