There have been many things that could be considered only ‘a local concern’, but ended up on national TV.
I can think of a couple of private plane crashes with only the pilot or just one additional person that did not impact the nation at large, but was still covered.
It is rare, very rare, that no one sees fit to mention it (assuming that is accurate) at all.
Mighty poor blackout:
