From everything we've read, there were drills previously and the fire station was the designated staging area...Even the running kids according to the videos on this post show us that the kids were running to the fire station...
And according to the videos on this thread, the police were already at the school...
Yes, but what I mean is, even if the kids were told that was the designated staging area, and that is probably why they ran in that direction, it was too early for anyone at the firehouse to have known what was going on and actually set up a staging area. If they had, I think the people at the staging area would have noticed the kids a few feet away and brought them inside, don’t you?
