As my colleague Liliana Segura noted on Twitter this morning, the documented killing of black Americans by police officers has become so routine that it is hard for even the racists who seek to justify the slaughter in online comment threads to keep up.

For the news media, one way to frame these stories as something new is to focus on the technology, which now makes it possible for eyewitnesses to record and disseminate the killings, and for those outraged by the images instantly appearing on their screens to register their discontent without even looking up from their phones.

That’s why the first reports on the killing of Philando Castile, a 32-year-old cafeteria supervisor at a Montessori School in St. Paul, Minnesota, who was shot while reaching for his license during a traffic stop on Wednesday night, included a comment from a Facebook spokesman. The aftermath of the shooting, as Castile bled to death in the front seat of a car, was streamed live on the social network from the phone of Castile’s distraught girlfriend.
