I mean an even more basic timeline. When did the police manage to get into the building? Did any police see the shooter or exchange shots with him?

That classroom building is huge. Was more than one door chained? All of them? That takes time.

On the assumption the mass murderer was CHINESE, the Chinese news media have already jumped into action, with timelines, graphics, explanations, etc.

(Japanese news media is also hot on this story, covering the reactions of many Japanese students who were on campus there.) No shortage of them having second thoughts about safety in American hinterland. Which is really said--the numbers of Japanese studying in the USA were dwindling already due to perceptions of lack of safety, which all of us here have tried to counter. Who could blame them now (at least those up there in the beautiful hills of Virginia today)?

The chef of police sais TWO doors were chained. I believe that statement was made in the 7:30 news conference.
