If policy was for that door to be closed and can only be opened from inside, that Teacher should be charged.
What is that teacher's name? Why was she outside to begin with?
Apparently it was a guy, mostly likely that door was the shortest distance to the parking lot. He could have been going out to his vehicle for any number of reasons. Could have been his lunch time.
Apparently he did not have a key or an ID that could be swiped to open the door. Most damning would be if he forgot his ID or school keys on his desk and thought “fuggit” and just propped the door open for a bit.
