I'm referring now to the video "Sandy Hook News Chopper Helicopter": [link to www.youtube.com] .

Let's take a look at this man, who stands to the left of a door of the firehouse and at 9:47 gets food from a lady. See the snapshot: [link to s1.directupload.net] .

And after that - like already before - this man always waves and beckons the people, who come out of the door to the right in the video, to go trough the door next to him.
Now: You would never give parents, who are happy that their kids survived but also still shocked about the massacre, commands of where to go next!
This even less as parents who just left the firehouse (and already had met their kids) have no reason to enter the house again!

This man has definitely the function of an organiser of a movie set, who (from out of view of the camera ) organises those actors who are to be "pedestrians".
In a real movie these "pedestrians" to be organised look like in this trailer at 0:13: [link to www.cinemagia.ro]

This proves that these people in the yard of the firehouse are not at all "parents" of the Sandy Hook Elementary kids but actors of a organized scene.

Also: We are told that all children, who survived (600?) are in the firehouse. But: 600 children could have up to 1,200 parents. And even only 400 children could have up to 800 parents. It is absolutely impossible to see between 800 and 1,200 parents before the firehouse!
