Sandy Hook: Kindergarteners Evacuated Behind Portable

This claim would be factually inaccurate. The kindergarten classes were on the east side of the building and evacuated through the northeast corner, which is at the front of the school. I am not aware of any class being evacuated through the route being claimed in this video.
