The videos exposing this as a drill get getting better and better. I don't think this video you posted is all that great. I wonder if Boston Globe still has that tweet up from the morning of the Marathon where they warned about a bomb drill that was going down the exact spot where the bomb actually went off. I remember I had heard of that and thought that if true they must have taken it down. But sure enough, several hours after the blast the Boston Globe still had the tweet posted. Unreal.
One of my fav videos is this one where a guy comes up to two guys who have their shirts off and are helping an injured person. He yells out a warning and you see one guy turn his head so he does not get it in his eyes. Then the powder man throws the stuff all over everyone so they look like they have been through a bomb blast.

Humanity truly is despicable that they are duped by these drills. And shows how people can be controlled with just a little bit of money.
And another thing, can't they find more realistic blood or develop blood that turns dark after a while? Notice how NOBODY has any dried blood ever in any of the photos. The blood on the ground is remains the exact same dayglo color regardless of how big the pool is or how long it has been sitting there.
