First reports are always wrong

That's a truism in my line of work.

Good discussion on this from Breach, Bang, Clear.

They hit the media (mainstream and social) pretty heavily, but it also applies to reports from on scene (first responders). Not though stupidity, ignorance or agenda as with the media, but due to the chaos inherent in a dynamic situation with multiple observers seeing the same thing from different angles, and usually have better things to do at the moment (like saving lives) to stop and do a complete analysis of what they are seeing.
