From the article:
“...FBI agents on site and police instructed witnesses to delete any video and photographs of the event and cleared out the bar, according to reports. Likewise, FBI officials instructed Austin Police to not release any details of the death to the media, sources confirmed. Witnesses at the nite club were also told to stay offline and keep quiet about the shooting,...”
Is this standard procedure, to tell people to delete vids & pics of this sort of thing?
Well, as a matter of fact...
Yes it is normal procedure. When a C-130 at Fort Bragg in 1988 or 87 crashed doing a tank extraction exercise in front of crowd from the 82d Abn Div they took media devices and removed anything. It happened at State as well when I was there.
Seems like destroying evidence, no?
