if the teachers had a key to all the locks, why did the custodian have to lock them in a room when the teachers have a key to do that and why did the woman say someone jiggled the door and moments later the teacher opened it, not unlocked it.

why did this supervisor teacher not know or have a key to rush everyone to safety behind a locked door classroom. instead the janitor did that and stood guard outside the door,

i know i would be out a there if i heard guns going off
