Someone recently claimed that regulations on press releases and press coverage are well founded, because the media too often prematurely publish information in a way that hurts a nation or individuals. So, I was wondering:
What are the major cases where a (well known/established) news outlet prematurely publishes a story, gets it wrong and in doing so creates substantial lasting political or (physical, financial, psychological) personal damage? Prematurely would mean that the media outlet likely acted in haste in hope of increased financial gain, severe sloppiness, for personal/political gain or similar non-journalistic reasons. Simply publishing a conclusion drawn from facts where additional facts later change the conclusion or some sufficiently established information assumed to be true turns out false would not count - if the conclusion was logical and well supported by the evidence. Neither do factually correct reports count that led people to draw wrong conclusions that the article did not state - unless they are by their wording implying these conclusions and the wording happened due to a premature/hasty publication rather than through intent (e.g. tabloid headlines just by their style would not count).
In addition, is there any statistical evidence that such cases have increased over time or decreased?
