Was this and other massacres "arranged" in order to advance an agenda.
Maybe yes in the context that certain pharmaceuticals have effects on the mind that, there is strong evidence, cause these horrors.
Yet, and here's the "arranged" aspect, there appears to be a disregard and even a coverup of the connection -- it could be argued that some in the ruling class New Normal want the shootings to happen
and among them there was talk that it may be necessary to kill as many as 60 million Americans to get their desired transformation of America. They need to disarm those 60 million Americans.
Just about the number that votes R every election, huh?
