Watch the bottom video (pay attention to the 1 minute mark and pause it there). And look at the story they are trying to tell. I can only assume it's to make people afraid and more susceptible to [DS] plans to be unfolded.
I am convinced that these are not real people (but rather realistic looking dolls) lying there after seeing the videos.
