The issue form most new stories is that even when the truth comes out, the great majority of people will never hear the actual facts. One issue is because news stations move on from caring about the story quickly. Or, the bigger issue in my opinion, is that people won't believe the new, correct facts since the old ones will have been engrained in their head. Solving both these issues would be really helpful for society, but are obviously damn hard to solve since we haven't really gotten anywhere in this space.
When there is such chaotic news story, I usually switch from news to Wikipedia. That has all the facts and continues the story even after all media lost interest.
