We are responsible for the environment of celebrity that rules our country.
Mass shooters become celebrities.
Victims and Witnesses become celebrities.
News anchors become celebrities.
Ex government agents become celebrities.
We have created a culture where people in these situations disregard their safety, instead live-tweet, live-stream, and even call in direct to news outlets with exclusive information like where they're hiding.

We have created a whorish news media full of psychotic vultures who tweet back during these "Hi this is Alison with CNN - have any of your classmates been shot? Can you call us?"
They've tried to scrub this from history but many of us screenshotted and saved so the future knows the full extent of what was happening at this point in time.
There's plenty to be suspicious of regarding this event and its subsequent cross-country, mass media marketing drive.
David Hogg's location throughout the day of the shooting isn't part of the suspicion.
