The “Unite the Right” rally in Charlottesville, Va., that exploded into chaos and violence that culminated in the death of a 32-year-old woman, ended in a matter of hours.

The onslaught of media reports about Saturday’s demonstration by white nationalists and its fallout, however, has stretched on for days. And there are few signs it will stop anytime soon.

Indeed, some of the coverage itself has become news — or at least commanded the internet’s fleeting attention. There was a horrifying still photograph of the violence, a chilling documentary video, and of course, a series of defiant tweets from President Trump that continued into Thursday.
