The issue of credibility is an important one. If a story that was broadly true can be picked to death by the PR and Legal departments of companies, then it places a real burden on the future of investigative and campaigning journalism. One minor mistake, plastered across the front page, will inevitably encourage readers to question the story more generally as it appears to suggest that both points of view have equal merit. A broadly true story of an industrial giant polluting the environment or a bank indulging in corruption is not negated by getting a single fact wrong. The company, of course, will use any detail to challenge the whole story, risking the reputation of the publication in the process. This may ultimately mean that journalists are simply much more cautious and so will not publish any stories that will likely bring about a response in the form of a reply from the target of the article.
