“5-b) Why were the kids in the Gym told to cover their eyes exiting the back of the building? “
So they wouldn’t see the dead children. That which is seen cannot be unseen.
That doesn't make sense. Why would they have moved the dead children outside, before evacuating all the live children? To quote the original post, "5.) According to the official story, the killing was tightly confined to two classrooms, near the front door and office. So why were so many children told to close their eyes while leaving the building through other exits where nothing was even close?"
