Not at all, that’s where the BS originated.
Then your post makes no sense. You saw this already with Columbine as it was filmed in real time.
“What really pisses me off is the kids who escaped being shot and dealing with the terror, but then having to join a fing human centipede chain to get out of the area, with their hands on the shoulders of those before them. I watched far to much footage of Nazi doing the same to the Jews. Is this conditioning for when it comes time to run to the ditch?”
It has nothing to do with the Nazi’s and everything to do with our current handling of school security protocol. Columbine in 1999 had the students in a human chain while escaping the school.Nothing to do with Nazi’s and the holocaust.
It didn’t originate there, either.
