The narrator uses a lot of pure supposition as the camera pans around, along with loaded imagery. Gas pipes (she says) located in areas that (she says) have never been heated before. Obviously, the idea is to conjure up fears of the WW2 death camps in Germany. Any old factory or defense plant that is no longer in use will look a lot like that. Security cameras, turnstiles, high fences with barbed wire at the top. It proves nothing except that some people have vivid imaginations. The fly-over by the "black helicopter" is the cherry on top.

If you want something that will really scare your socks off, try this. Just because it starts out looking like a car commercial, don't let that fool you. You'll get there soon enough.
