The minute they blamed it on ISIS, I knew it was yet another false flag:
The people running away are like actors in a movie….oh, wait….
And the second video states there was a practice drill three days before…wow, what a coincidence! /snark
And, of course, the actors wearing their number badges gives them away as being fakes. Good Lord.
Of the videos I have seen, and comments on them, they haven’t made mention of March 22 as being the birthday of Mary Magdalene….hmmm….I wonder….
